We previously opened permission for anyone to edit the FAQ, but there was a hole in that which allowed someone to post an attachment (some MS virus most likely) on the front page of the wiki.  We tightened things up a bit, but it looks like perhaps we made it too tight.  Looking into it...

Weird.

There was actually no crash.  The log file that you attached shows normal startup progress.  The "crash" report that you attached is actually a spindump.  These occur if you force-quit an application which appears to be in a locked state (usually this means the main thread is doing something that is taking a long time like a synchronous DNS lookup or disk I/O).

From what I can tell, we were just spending a lot of time deep inside CoreCraphics in the run loop ... perhaps the WindowServer was being overloaded or was otherwise taking a while to respond...  Patience might've won out in the end
