Try changing your thread detaching to just calling the method directly so it's in the same thread, lets make sure it's a threading issue and not something else.

Hi Michael

Yes I get this when I change the selection in the table view too quickly:

"encountered unexpected object type: 7. missing or invalid object number. invalid `Kids' array: missing or invalid dictionary at index 0."

gdb gives all sorts of different reports on what caused it but the one that comes up the most is: mach_msg_trap

I did try to introduce a delay to see whether this could help but still got a crash. selected file in the code below is my method that does all the selection handling in the table view.

- (void)tableViewSelectionDidChange: (NSNotification *)notification
{
[self performSelector:@selector(selectedFile:) withObject:nil afterDelay:0.1];
}

I will do the UI animation in the main thread as you suggest.
