You could have send that back trace inside your mail. It is small enough
to include it:

This segmentation fault happens right after loading the XIB file, so it
could still be related to that :-(
Most likely we are releasing stuff to eagerly and that makes the
difference to the Gorm loading. Could you please try to compile your XIB
file into a NIB file on you Mac and test with that too? That way we
could narrow it down to either  shared or separate code. The NIB code is
a lot more mature, so hopefully only the XIB will be affected.

Heh. It's unbelievable. I was about to send this mail anyway, since
yesterday I had some time to play with this (at last!). Sadly, I didn't
update to latest GNUstep and I didn't send the mail yesterday or earlier
today, since I don't have proper Internet connectivity at home.

I couldn't fix anything, but I produced this backtrace:
It's not very useful, and doesn't seem to be related to XIBs. It does not,
however, occur with loading GORMs, so it is surely related at least a bit.
