That's the case now, there was a bug in the logic of the 
_QT4_ADJUST_LIB_VARS().
This doesn't mean the issue is really fixed, but it will happen only to people 
which really have both the release- and the debug-versions of the Qt 
libraries installed (I guess mostly Windows developers ?).
Of course we will have to fix that too.
