I'm mystified too.  Sounds like raising a bug might be your best bet; it 
may be come across by someone who knows more or recognises something.

Looking at your sh -ex runs, good and fail, the only thing I wonder 
about is whether running it without -e might make any difference ..
although the sourced /etc/rc.subr certainly should be -e safe.
