Bug 363422

Application: plasmashell (5.6.4)

Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.4-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160422) (x86_64)"

-- Information about the crash:
This crash occurs on login. I have a dual monitor setup and when this occurs the desktop is mirrored on each screen. I have an NVIDIA card I can use nvidia-settings to get the desktop to span the two screen but I get visual artifacts on the icon text on the desktop. Everything else works as expected.

The crash can be reproduced sometimes.

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