Description Nick Stefanov 2018-05-23 19:13:27 UTC

Application: plasmashell (5.12.5)

Qt Version: 5.10.1
Frameworks Version: 5.46.0
Operating System: Linux 4.16.10-1-ARCH x86_64
Distribution: "Arch Linux"

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

Sometimes (often) Plasma crashes on qbittorrent exit via right click->exit. It often crashes too at widget change - enable or disable.

The crash can be reproduced sometimes.

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