I inserted
[NSException raise:...]
in NSView where it complains about the given negative widths and got
#1 0x00007fabaac53bba in +[NSException raise:format:arguments:]

...
The related code is
NSTabViewItem *tabViewItem = [[NSTabViewItem alloc]
initWithIdentifier:identifier];
[someTabView addTabViewItem:tabViewItem];
[tabViewItem release];
Hmmgh! It seems that NSTabView calculates some unhealthy frame here. Can
anybody with insights see whether this is related to the rest of the error
chain?
Thanks,
Andreas
