I fully agree with you that the core issue is probably elsewhere, most likely where

Unfortunately I don't know yet where exactly, so as starting point I notified the nose devs.

Also, I wasn't yet able to pinpoint the segfault.
So far AFAIU looks like a memory corruption which later let the VM crash badly.
