This is a known problem with Qt apps on KDE. When the Oxygen theme is trying to 
be loaded, Qt tries to load it natively from the system, which relies on the 
system Qt libraries, which wont mix with the ones that ship with IEP.

I can make IEP start a bit further by setting the default Qt theme to 
cleanlooks using the qtconfig tool. But then it crashes again...

I found things that go wrong:
1) the qt theme cannot be set to Oxygen
2) the file browser and project manager use a QFileIconProvider, which also 
triggers into using the system libs when an icon for a file on the filesystem 
is requested.

I made fixes to make things work, but there is still one problem: You still 
need to unset Oxygen as the default theme using the qtconf util. Otherwise the 
QApplication cannot even be created.

Oh wow.  The solution is embarrassingly simple: put a qt.conf next to the 
executable to disable the qt plugin directory. Like magic, all problems are 
solved. 

The Oxygen theme can even be the active one, but it will simply be ignored. The 
file icons in the file browser are simply the default file icon.
