under a new wine prefix during the installation of .NET2 with winetricks it ended again just that way: wine: Unhandled exception 0xc06d007e at address 0x7b844f70 (thread 0084), starting debugger... wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart. I'll revert to my old prefix and an old wine version until that is taken care of...
