Comment 1 Ludovic Grossard 2011-12-02 12:33:46 UTC

oups, please replace 
click on Application Appearence 
by
click on Workspace Appearence
in Steps to reproduce

sorry.

Comment 2 Hugo Pereira Da Costa 2011-12-02 14:34:44 UTC

It's a build issue.
See: 
#6  0x00007f92e896d598 in Oxygen::Helper::invalidateCaches() () from
/usr/lib/liboxygenstyle.so.4

whereas your kde build log indicate: 
/home/kde-dev/kde/lib

Most likely the loaded plugin is incorrect.
Check: $HOME/.config/Trolltech.conf 

[qt]
4.7\libraryPath=...

Make sure its empty.
Keep me posted and close the report when fixed.

Comment 3 Ludovic Grossard 2011-12-02 19:39:46 UTC

Indeed, adding
[qt]
4.7\libraryPath=

to $HOME/.config/Trolltech.conf fixed the problem. 
Thanks a lot for the hint.
