            Bug ID: 362718
           Summary: Systemsettings 5.5.5 crashes when Switching between
                    two menu items
           Product: systemsettings
           Version: 5.5.5
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: wettererschein...@bb-goettingen.de

Application: systemsettings5 (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
Bug #354164 sounds similar, but there it stated that the error is solved in
Version 4.x (I don't remember exactly). So as I am using Version 5.5.5 it can't
be the same bug, no?

Every time I go to the desktop settings and switch several times (not only
twice as in the other bug) between some entries after 6-12 changes it crashes.

- Unusual behavior I noticed:
* Switching between Breeze and Breeze-dark doesn't work properly. This results
in a mixup between the two and the layout changes every time I click on the
other theme, click back to the active theme and apply the "change".
* Plasma crashed two or three times without me being able to tell why or in
which situation.
* Grafics are disturbed (Some texts inside a button are longer than the button,
in Discover the descriptions of the top presented items above are not readable
because the overlap outside of the boxes, Ubuntu Software Center shows white
text on white background which makes it unusable)
* Theres a cracking noise out of the speakers after login, when initialising
KDE.

The crash can be reproduced every time.
