Description resident.evil.mattew 2018-10-25 02:49:36 UTC
Application: plasmashell (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-34-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
I was looking for a file inside a subfolder of my Home directory.

The folders expand when clicking in the arrow at the left top of the icon, so after finding my file I dragged it into the Desktop. Then the crash occurred and Plasma restarted

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
