Description Matt Scheirer 2017-10-17 16:23:30 UTC

Application: plasmashell (5.11.0)

Qt Version: 5.9.2
Frameworks Version: 5.39.0
Operating System: Linux 4.13.6-1-ARCH x86_64
Distribution: "Arch Linux"

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

Whenever I suspend / resume my desktop on 5.11 the shell crashes but does succesfully restart. Didn't happen on 5.10, and I didn't change any settings betewen the upgrades.

- Unusual behavior I noticed:

I noticed similar crashes when trying out the Wayland session when unlocking and resizing the panel, but this suspend crash happens on X and I can only infrequently crash the shell resizing plasmoids on X.

- Custom settings of the application:

None

The crash can be reproduced sometimes.

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