Reproduced. I didn't need to have any slides. The major problem here is that your Impress becomes completely broken - you can never ever move the pane. Anytime you touch the header bar of that pane, Impress crashes again. The only solution is to delete the configuration files (or switch to X11).

Moving the panes in LO is pretty common, I'd think. Also, this does not just crash, but makes your app broken even for future launches (you can never move away the floating pane or put it back, even when it obstructs your view), which is a much bigger problem.

I disagree. I think that tearing off the slides pane is rather uncommon. If I've ever done it, it was unintentionally (just like the reported case). And I've never seen anyone else doing it either.

It is always possible to dock the pane again. Press Ctrl and double click inside the window or press Ctrl+Shift+F10. (It took me only a few seconds to find this in the help, btw.)

Shrug. I do it all the time. The defaults are not to my liking.

> Press Ctrl and double click inside the window 

Doesn't work for me.

> or press Ctrl+Shift+F10

That does work (mostly, sometimes I had to press it several times). However, you only found it because you knew about the bug and knew what you're looking for. That will not probably be the case for most of our users - if it crashes during drag&drop, I wouldn't realize I can try a keyboard shortcut I don't even know it exists (I certainly didn't).

You can't move the panel when its floating because of https://bugzilla.gnome.org/show_bug.cgi?id=768098

If you could move it, you couldn't dock it again because of https://bugzilla.gnome.org/show_bug.cgi?id=768128

Confirmed with LO Writer. I can undock the toolbars and move them around just fine (no crash), but there are no hints for docking and thus it can't be docked easily (drag&drop). Unfortunately there's no button "dock again" either. Double clicking on the toolbar header docks it again (but that is not completely obvious). By reading the bug, it seems this will not be an easy fix.

However, if we can resolve the crash, we're definitely in a better position (people will start looking for a way to dock it, instead of just seeing it crash every time they touch it).

Seems my upstream https://bugs.documentfoundation.org/show_bug.cgi?id=98807 fix for something else is the reason master doesn't crash on this type of interaction

I'll make it "not crash" as the solution for this

The crash is fixed.

I've created a separate bug 1391418 about this. This issue seems important enough to have it covered in our common bugs page.

I'm 0 on blocker status. I'm not sure it quite meets the burden of "basic functionality". I am however +1 FE. We should get this crash fixed since we have the patch ready.

libreoffice-5.2.3.3-3.fc25 has been pushed to the Fedora 25 testing repository. If problems still persist, please make note of it in this bug report.

Discussed during the 2016-11-07 blocker review meeting: [1]

The decision to delay classification of this as a blocker and instead classify it is an AcceptedFreezeException was made as there was question as to if this bug merited a blocker status, however there is a fix released, so marking this bug as a freeze exception and moving forward was deemed appropriate.

Is this a duplicate of my Bug 1388761 ??!

Yes it is. No need to put needinfo on the reporter.

Bodhi didn't close the bug for some reason, closing.

Can you re-size the un-docked window? Is the normal behavior to be fixed-size?

I can't resize it. I think it's yet another wayland-related bug. Please try whether it works on X11 and if it does, please report it as a new bug, thanks.

It's not resizable on X11 too. but when it gets un-docked, it gets the same "usable" size every time. However, in wayland, it takes good size the first time, but not the second time (or any times after that).

I think my previous bug report is still valid!
