Description of problem: I haven't tried to reproduce it yet, but these are the steps: 1. Boot a qemu-kvm guest (the system is an updated Fedora Rawhide). 2. Log in to a Gnome+ Xorg session. 3. Abrt catches the crash.

I cannot reproduce your backtrace in the latest fedora 24. Are you still able to reproduce your backtrace?

I confirm that, with an updated Rawhide, I'm unable to reproduce this bug.
