odd crash on makeKeyAndOrderFront:

FROM : Josh Anon

I've got an app with a main view, and when I double-click on some
icons, I want new windows w/ an image view to open up.  To do so, I
have a controller that loads the nib in its init method, shows the
window when -showWindow is called (by calling makeKeyAndOrderFront),
and everything seems fine.  It mostly works without a problem, but
sometimes it crashes with in the -makeKeyAndOrderFront: method (crash
log included below).  However, when I make an empty subclass of
NSImageView and change my image view's type, it crashes nearly every
time when I try to show the window.

Has anyone seen this before or does someone have any idea what I'm
doing wrong?

Thanks!
Josh
