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.
