--- Comment #1 from Louis Lenders xerox.xerox2000x@gmail.com --- Created attachment 62376 --> https://bugs.winehq.org/attachment.cgi?id=62376 patch that fixes the crash
Attached a patch that fixes the crash. Just make sure that hIcon is not NULL (as the crashlag said..), and the crash is gone.
Not sure if the patch could be improved, comments welcome
