I just see the line "wine: Call from 0x... to unimplemented function ntdll.dll.CsrClientConnectToServer, aborting"
No backtrace follows, because of an issue with eoc and winedbg (different bug)
The key part is "from 0x...", the address the API is called from will help to figure out who is calling, especially when you run under winedbg.
