Description Vivek Saxena 2015-07-28 11:45:12 UTC

Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.2-2-ARCH x86_64
Distribution (Platform): Archlinux Packages

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

- Unusual behavior I noticed:

- Custom settings of the application:

The Plasma shell taskbar crashes every now and then. This behavior is reproducible, but doesn't happen when one is using any specific set of applications.

The crash can be reproduced every time.

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