Yes, you can close this ticket. I think this is not bug of GHC, it's problem of `forkProcess` implementation. Because `forkProcess` is not a safe function to spawn process.
I'm developing Haskell Application Platform (multi-processes framework with DBus), i use `runProcess` spawn child process, i test it with GHC-6.12 everyday, works perfect. Please attach my notes when you close ticket, then other people won't get same trouble with `forkProcess`. > >>> I can't use the latest release of gtk2hs because it doesn't work with GHC >>> 6.12.x.

Yes, cabalized version is cool, that's mean Windows and Mac can install gtk2hs easily.
