           Summary: WaveLab 4 crashes at startup
           Product: Wine
           Version: 1.5.11
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED

After some time of working fine in wine, WaveLab is now crashing every startup.
I've traced this problem to start at this commit:
6bfcb347bfff24d7268e23b3686028373631c642 is the first bad commit

See several tries to start it (they give different output depending on whether
it's a first start after installing wine): http://pastebin.com/fBkGEZbh .
Reverting the commit makes it work normally.
