Description Andrew Kaiser 2017-05-30 21:43:09 UTC 
Application: plasma-discover (5.10.0)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: KDE neon User Edition 5.10

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

Searching in the Discover application crashes intermittently. This is usually after searching for an application and not finding a match, then searching again without changing active panes in the application. The second search may or may not have results, but the application will usually not get to that point.

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".

I have experienced a very similar problem. Searching for "calculator" causes a crash every time (some results are shown).

plasma-discover (5.10.0) using Qt 5.7.1

Searching for an 'ktouch' application in the search bar, the application stopped responding and crashed

I can reproduce this 100% by searching for "inkscape".
Comment 13 Dan Leinir Turthra Jensen 2017-06-22 10:31:02 UTC 
Fixed as a side effect of https://phabricator.kde.org/R134:efaa09a20543583323cdc8f7841a0879faed0d37 which removes the code-path that triggers this particular crash.
