Comment 14 Felix Schwarz 2016-02-13 18:29:52 UTC 
Daniel: In bug 1301730 the reporter mentioned that reinstalling "python and glib packages" (sudo dnf reinstall ...) fixed the problem for him.

While I understand that this is not real fix and the problem is very real (given that FAF counted 7567 occurrences) it might help you.

@raphgro: Given the FAF statistics it seems this is also connected to the -rc upgrade. We need to fix these problems urgently. IMHO you should consider even pushing a downgrade to stable if we can't develop a real fix (and given that upstream is pretty much dormant I think there won't be help from that side).

Comment 16 Raphael Groner 2016-02-13 18:38:57 UTC 
Bug 1301730 was reported earlier for rawhide, so this bug (as a duplicate) is obviously in rawhide.
Comment 17 Daniel Seither 2016-02-13 21:36:59 UTC 
I tried reinstalling python and glib2, but to no avail. I temporarily "fixed" the problem by downgrading hamster-time-tracker from 2.0-0.2.rc1 to 1.04-5.

If someone else needs to make hamster work again until there's an update:

dnf downgrade hamster-time-tracker
dnf install 'dnf-command(versionlock)'
dnf versionlock add hamster-time-tracker

The package can later be updated with

dnf versionlock delete hamster-time-tracker
dnf update
Comment 18 Felix Schwarz 2016-02-13 21:40:03 UTC 
Thank you very much for your effort. I'm debugging this for a few hours and we identified the root cause (which is a glib/gio problem). A assume a Fedora workaround will be added soon-ish.
Comment 19 Daniel Seither 2016-02-13 21:46:36 UTC 
Great, thanks!
Comment 20 Raphael Groner 2016-02-13 21:49:31 UTC 
As discussed in IRC, the bug is found in glib2. Same reason for bug #1307253, that should be fixable with the workaround mentioned there.
