Review request for KDE Frameworks, David Faure and Scarlett Clark.


Repository: kwidgetsaddons


Description
-------

The kdualaction autotest fails, when the icon was not found in the current theme.

The reason is that KGuiItem returns a newly created Null QIcon() when passing any Null icon to setIcon().

Use a fallback icon instead.


Diffs
-----

  autotests/kdualactiontest.cpp 6b16c89 

Diff: https://git.reviewboard.kde.org/r/128548/diff/


Testing
-------

Passes with all eight combinations of:
- "kde" icon present/not present
- platform integration present/not present
- Qt 5.6.1 tag/Qt 5.7 branch


Thanks,

Christoph Feck
