Bug 353763

Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.1.10-200.fc22.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I applied the latest Fedora 22 package updates today and rebooted. When I logged in I was greeted by this crash.

bug 352826 seems to be related, that looks like a similar cash in the nuveau driver instead of r600 here.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
