(In reply to comment #20) Source/Steam command line switches help. Toy with them. Eg: wine portal2.exe -nobreakpad -nocrashdialog -nominidumps
Breakpad is the Source debugger. Also worth noting are -nosound, -novid and -window.
Yeah, I tried experimenting with most of those options before and I just tried the others - there's still no useful information that's output. It seems like the application might be intentionally terminating for some reason :/
