Sentry Crash Report:

Description Jan-Matthias Braun 2017-05-07 21:11:15 UTC 
Application: krunner (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.33.0
Operating System: Linux 4.10.14 x86_64
Distribution: "Gentoo Base System release 2.3"

-- Information about the crash:
1. Open krunner via shortcut
2. Enter sys (for systemsettings)
3. Move the mouse over the dialog
4. Wait
5. Move the mouse outside the dialog

Steps 3 & 4 seem optional.

This procedure seems somewhat bizarre to me. Or even ridiculous. But when I just open the dialog, enter a string and press enter, then everything works. The mouse movement seems necessary to trigger the bug. Touching the dialog not, although I do not see the problem when waiting after mouse movements over the dialog.

Maybe it is just a timing issue with a search plugin. But without mousemovements everything seems to be fine.

Distribution is Gentoo. Packages are up to date. Compiler flags are standard (O2, native arch).

The crash can be reproduced every time.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

It's subtly different, it's in allProperties, but the stack is *not* in Qt code after that. Therefore it's not the same thing.

Hi! By now, after updating to kde frameworks 5.35 and plasma 5.10.2, I am unable to reproduce the issue.

So, whoever fixed it, thanks a lot!
