WINEDEBUG log (ole,strmbase,gstreamer,quartz,mfplat)

Something odd is happening here.
A WolfRPG game that works fine for the most part, but in one place it freezes.
This happens upon a map transition, which implies a BGM change.
The freeze is a never ending MediaEvent_WaitForCompletion.

Odd part is that upon disabling winegstreamer via WINEDLLOVERRIDES, the sounds
continues to work (probably going through dsound filter), but the freeze is
averted.

The last log entry before sequence that triggers the freeze in the log is 'is
being unloaded while mapped' line.
