I’m not sure what the sigtramp signifies. My first guess would be it’s a side effect of messaging a dealloced object.
Just one of the (multiple) reasons I despise the "afterDelay" version.
Almost every crash I see is directly (or indirectly) caused by using performSelector:withObject:afterDelay: to insert some kind of "pause" in the application, and that pause isn't cancelable (AFAIK) -- the selector WILL be called after the delay time, even if the user has moved to another part of the program.
