Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general

-- Information about the crash:
- What I was doing when the application crashed:
had just logged in, and was looking at software sources in the Discover app.
This happened a week ago too, but the crash handler couldn't provide any kind
of useful report at that time.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
