I once had this problem and it was triggered by an unimplemented function in msvcrt. Did you tried running with --debugmsg +seh? But better redirect the output to a file.
Nope:
wine client error:0: trace:seh:EXC_RtlRaiseException code=c0000005 flags=0 addr=0x4009e977 trace:seh:EXC_RtlRaiseException info[0]=00000000 trace:seh:EXC_RtlRaiseException info[1]=00000018
It's just a plain old access violation...
