Excellent patch, thanks a lot.

This doesn't only solve the dependency on oxygen-icons, but also the failure 
due to that test picking up stuff from another kdelibs subdir when it was all-
in-one.

An alternative to "copying files from the resource into a temp dir that has to 
be cleaned up afterwards" is to just have the icon theme files in the source 
dir and use QFINDTESTDATA to find the root of it. But you wrote one solution 
already, and I'm fine with it, so: Ship It!
