From ClientGM:

You can send the logs to me and I'll forward them. Sorry about the problems.Please send the crash logs.
In 10.4 they're in {$HOME}/Library/Logs/CrashReporter/, but I forget if
they're still there in 10.5, or if they got moved to, e.g., the analogous
place in the top-level /Library folder. Regardless, Console.app ought to
know where to find them.
