How do I prevent this crash? It happens occasionally when I call
[NSView nextValidKeyView] or [NSWindow selectKeyViewFollowingView:]

My keyloops are calculated automatically by NSWindow. One of my
windows has an NSSearchField in the toolbar, another has preference
pane style buttons. Both windows have crashed with this bug.
I sometimes move the keyboard focus programmatically as the user
selects things from pop-ups, etc. In the crash above I'm moving the
keyboard focus to an NSTextField in a subview of the main window in
response to an email arriving.
That '%' in front of NSToolbarView's name means somebody is posing as
NSToolbarView. Try turning off whatever hack is doing that.
