Description astro.simone 2014-10-01 09:35:26 UTC 
Description of problem:
I installed akmod-nvidia kmod-nvidia packages via RPMFusion.
the problem started at the next reboot.
it didn't start login of gdm, but there was one message.
it was said that an error has occurred and you have to logout.
even if you restart gave me the same error.

I have moved in another shell and I removed the installed packeges and restart normally.

Comment 13 Parag Nemade 2014-12-23 08:17:07 UTC 
Works fine for me. I am closing this since we got a new caribou-0.4.16 in released Fedora 21. Please test against it and if found bug, report against caribou-0.4.16 version.
Comment 14 Parag Nemade 2014-12-23 08:18:05 UTC 
Ah sorry I thought 0.4.16 is part of released f21, but its an update.
Comment 15 Bernardo Donadio 2014-12-25 17:06:36 UTC 
The bug is still present in 0.4.16.1.
Comment 16 Parag Nemade 2014-12-26 04:15:57 UTC 
Hm. But I still don't know how to reproduce this bug. Try reporting this in upstream bugzilla -> https://bugzilla.gnome.org/enter_bug.cgi?product=caribou

Thanks.

Well, we already have a bunch of such bugs in upstream and no further reporting is needed (also you might want to try reporting to "at-spi" component instead of "caribou").

I believe the crash will go after this gnome-shell patch being backported:

happens in recent F21, just in fraction of second after after another bug https://bugzilla.redhat.com/show_bug.cgi?id=1177495.
