Note, at this point _delegate will be 0xdeadface because the

Now, my question is - is this a GNUMail bug (i.e. the NSToolbar
should have been deallocated earlier) or is it a problem with the
GSWindowDecorationView removeToolbarView? Perhaps there should be a
check if the delegate still is valid before calling setFrame?
I'm not really familiar with the code concerned, but from your
description it sounds like the bug is in EditWindowController
If EditWindowController has set itsself as the delegate for a window,
it should also have removed itsself as the delegate at the start of
its -dealloc method.
It's a firm rule that an object must remove itsself as a delegate of
any other object before it deallocates itsself.
