Bug ID: 416408
Summary: Discover crashed after unlocking screen
Product: Discover
Version: 5.16.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: lei...@leinir.dk
Reporter: b.raz...@gmail.com
CC: aleix...@kde.org
Target Milestone: ---
Application: plasma-discover (5.16.5)
Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-26-generic x86_64
Distribution: Ubuntu 19.10
-- Information about the crash:
- What I was doing when the application crashed:
I had just unlocked the lock screen (computer was awake, just locked) and
opened the discover software repository application and used the search bar to
look for some software. The application began to search for software when the
screen changed to 'please check your connection'. It then hung and crashed. At
the time I was downloading a large file in Mozilla, so perhaps
bandwidth/latency was an issue. The problem did not persist afterwards, as I
immediately reopened discover and was able to find the software on the 2nd
attempt. Not really a priority bug, since I can't seem to reproduce it.
The crash does not seem to be reproducible.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
