EXC_BAD_ACCESS when calling pushViewController

Question

I have UITableViewinside a UITabBarController.

When i call

[[self navigationController] pushViewController:myViewController animated:YES];

no problems.

But, when I call the same line from within UIActionSheetDelegate, for example:

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex

I get it EXC_BAD_ACCESS.

It seems that calling this line from another thread is causing this problem.

How can I prevent this problem EXC_BAD_ACCESS?

(note that myViewController is NOT nil or something like that)

thank!
