Description Daniele 2019-04-06 12:28:39 UTC

Application: plasma-discover (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-4-amd64 x86_64
Distribution: Netrunner 19.01 - Blackbird

-- Information about the crash:
Just browsing the list of (installed) apps. Discover seems to be randomly crashing, as I couldn't find any culprit as to what might be triggering this behaviour.

The crash can be reproduced sometimes.

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