Comment 6 Parag Nemade 2011-04-25 03:18:23 UTC 
I see the easiest solution for this bug for now is to execute following on
command line.
gsettings set org.gnome.desktop.interface toolkit-accessibility true

Above will enable accessibility support in F15 and you can then run caribou
without a problem.

Crash notification appeared on first login to a KDE desktop after installing F15 with all four major desktops enabled.
Comment 16 Adam Williamson 2011-05-04 23:31:35 UTC 
Nominating as a final release blocker, per criterion:

"In most cases, there must be no SELinux 'AVC: denied' messages or abrt crash notifications on initial boot and subsequent login (see Blocker_Bug_FAQ) "

This notification popped up for me on first log in to KDE (a 'supported' desktop) after installing F15 Final TC1 DVD, with all desktop environments checked.

That will have absolutely no effect under KDE, for 2 reasons:
* This is a GNOME setting. You have to set the GTK+ setting directly instead. (AFAIK, the easiest way is an environment variable.)
* There are few to no GTK+ apps running under KDE normally. For Qt, you need
qt-atspi2, which is not packaged in Fedora yet. (It became usable only very recently.) You also need to set yet another environment variable.

In addition, the toolkit developers must have a reason to disable accessibility by default, I don't think it's a good idea to have something installed by default (when installing from the DVD) enabling it. (If we really want that, we should do it in the toolkits themselves, but again, this should be discussed with upstream.)

Caribou should exit cleanly instead of throwing an exception if accessibility is disabled.

Another solution for the blocker might be to just make caribou's autostart file OnlyShowIn=GNOME; for now.
Comment 20 Kevin Kofler 2011-05-05 05:09:47 UTC 
To sum up what we found on IRC: The problem is that /etc/xdg/autostart/caribou-autostart.desktop contains:
AutostartCondition=GSettings org.gnome.desktop.a11y.applications screen-keyboard-enabled
which is ignored by non-GNOME desktops, so Caribou gets autostarted unconditionally on them.

KDE has its own autostart condition implementation, which doesn't support this entry. (All the KDE .desktop files I see have their autostart conditions encoded with X-KDE-autostart-condition, which has a different syntax and always uses KConfig.) And XFCE probably doesn't support autostart conditions at all.

So it really looks like this should be OnlyShowIn=GNOME;.
echo "OnlyShowIn=GNOME;" >> $RPM_BUILD_ROOT%{_sysconfdir}/xdg/autostart/caribou-autostart.desktop
should fix this.

Still crashing when called from terminal (GNOME3)
Comment 27 Adam Williamson 2011-05-07 01:21:06 UTC 
well, yes, but that's not really a problem (though passing an exception to tell the user something is a bit inelegant). the problem was that it was being auto-started in non-GNOME environments.

Comment 28 Othman Madjoudj 2011-05-07 16:49:31 UTC 
Yes, caribou still crash when it launched from terminal, but after the last update it's no longer enabled by default on other desktops (tested with KDE).
Comment 29 Othman Madjoudj 2011-05-07 17:04:38 UTC 
It seems that the new version of caribou require clutter which require hardware acceleration, this why its crash in fallback mode or other desktops.

Output before the python traceback:

Clutter-CRITICAL **: Unable to initialize Clutter: Unable to select the newly created GLX context
Comment 30 Kevin Kofler 2011-05-07 20:49:52 UTC 
The problem on other desktops is actually not that Clutter is required, but that AT-SPI is required (see the text of the exception quoted in the subject of the bug report).

Clutter should work fine on other desktops if and only if OpenGL is working properly. Of course, since gnome-shell is actually based on Clutter, if your hardware cannot support gnome-shell, it likely cannot support other Clutter apps either. In your case, it looks like you don't have OpenGL working at all. (Is this a virtual machine?)

Yes, it's a KVM guest, It's not an issue since I generally use KDE for testing (sometimes openbox), this was out of curiosity.

start caribou via shell
(to test bugfix)
Comment 35 Kevin Kofler 2011-05-09 07:08:00 UTC 
Once again: It is expected that Caribou will still throw an exception if you run it manually without the requirements (working support for AT-SPI and OpenGL) being met. What the update fixes is that Caribou was getting autostarted by default on non-GNOME desktops.
Comment 36 Fedora Update System 2011-05-10 03:23:34 UTC 
caribou-0.2.00-3.fc15 has been pushed to the Fedora 15 stable repository.  If problems still persist, please make note of it in this bug report.
Comment 37 Felipe Contreras 2011-07-20 15:29:19 UTC 
I have caribou-0.2.00-3.fc15, the problem is still there, but I can't reopen.
Comment 38 mdmpsyd@gmail.com 2011-10-31 23:49:20 UTC 
I also have caribou-0.2.00-3.fc15 and continue to have this problem.
