My guess was right, something else is wrong.  You're initializing an  
NSMovieView with a Carbon.Qt movie.  That's very dangerous, when the  
Carbon.Qt movie gets deallocated, it destroys it, and the NSMovieView  
will be very unhappy about that.

The general rule is to avoid Carbon.* or anything that depends on it  
unless you absolutely positively have to, and you know what you're  
doing.

Basically, Don't do that.  Don't use EasyDialogs either.

To allow the user to select a file, use NSOpenPanel.  To initialize a  
movie, use NSMovie's initWithURL:byReference:.  With those two  
changes, the app should be less code (well, maybe about the same,  
depending on how you write it), will behave more natively, and it  
won't crash.
