-- Information about the crash:
- What I was doing when the application crashed:
I started "Discover" app as there were updates to install, it showed main
window, process some data (i don't know what data, because it doesn't show - i
heard fan spinning faster than usually) and after w while (10-15 seconds) it
crashed. That's all.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
