maybe I should have spelled it out more clearly. I don't have that much of a
problem in general with my code crashing when I update to the latest version of
the tree, as long as isn't something that could easily be avoided. And I've
spent/wasted too much time debugging memory management related bugs in
Objective-C code (mostly outside the GNUstep libraries) so that I've lost
tolerance for such bugs these days. Therefore, I keep pestering people with
requests to switch to ARC when encountering such bugs.
Now regarding your fix it turns out I had missed it because I hadn't update my
local from github since early December. But then updating the code, I'm afraid
your fix doesn't really solve the issue. The main problem is that _selectedItem
may be dead after the statement
ASSIGN(_menu, menu);
in method setMenu: and the code may setState: on _selectedItem in the
selectItem: method when altersStateOfSelectedItem is true for the pop up
button, which, unfortunately, is the default since commit 7023c7d. :-(
I've committed another fix to resolve this issue. I had intended to create a
pull request for this, but I've accidentally committed it to master right away.
Feel free to update the code as you see fit.

No, it doesn't happen for a standard GNUstep application. And while it is
reproducible for me (in at least one case), it seems rather difficult to narrow
it down. I've tried to come up with a minimal example today, but without luck
so far (the examples were apparently too minimal). In fact, the split view may
just be a red herring and the real problem may be lurking elsewhere. So don't
bother trying to come up with a test case yourself.
