Sentry Crash Report:

Description pavestnavi 2017-02-01 22:05:54 UTC 
Application: plasmashell (5.9.0)

Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.9.3-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I was configuring the applications menu to try and integrate it to my desktop.

- Unusual behavior I noticed:
It crashed plasma. The button in button mode didn't have an icon and the full menu's text is off.  

Also, the mouse focus in the full menu is off by at least one button. That is, where buttons are "File, Edit, Insert, etc.", if I hover over "File", it will show "File" highlighted, then if I click on "File", it will do what you'd expect, but if I move by a single pixel while staying on "File", it'll switch to "Insert". The box it creates has proper focus, and I have to move significantly to the left to properly select "File".

- Custom settings of the application:
It crashed once in full menu mode, but crashed several times in button mode.
I have a sloppy focus config that might be related to it, since it might somehow switch focus to the bar while it's not expecting it. The focus is set to "follows mouse - mouse precedence" delayed by 100ms.

I just want to say that I really appreciate all the work that you put into this and the Plasma desktop is making a lot of great progress. It just keeps getting better and better and never stales. I don't expect my software to be bug free especially when I get it this early, but I can't wait to see what the future holds. It has a lot of potential and I believe that with this much improvement every release it's making good use of that potential. Thank you very much.

The crash can be reproduced every time.
