Review request for Plasma.


Repository: oxygen


Description
-------

Valgrind pointed out ~ShadowHelper uses _helper, but at the time ~ShadowHelper is called, _helper has already been deleted. Deleting ShadowHelper manually works around this problem. I also have an alternative patch which turns _helper into a QSharedPointer, which I can submit instead, but the changes are much more invasive.


Diffs
-----

  kstyle/oxygenstyle.cpp 972e4c8

Testing
-------

Running "valgrind kcmshell5 desktop" does not print any error about invalid reads in ~ShadowHelper anymore.


Thanks,

Aurélien Gâteau
