Re: latest theme changes make Thematic crash

[Fred Kiefer]

I don't think that this problem is related to the NSImage changes.

What happens here is that a window gets closed that was key and main 
window and had a delegate. In that process the key and main window state 
get transferred separately. This leads to the menu getting updated while 
the old window is still main. Now the delegate of that window gets 
referenced and this delegate seems to be invalid at that point. To find 
out, what this delegate is and why it is already deallocated one needs 
to know more details about the application. Or run it with NSZombie enabled.
