Just a quick update:

I've managed to reproduce this on a jessie/sid system. Basically it 
seems to be caused by a combination of libcurl3-gnutls linked against 
libgnutls-deb0-28. Installing libcurl3-gnutls <= 7.36.0-1 (not -2) or 
rebuilding curl 7.37.0-1 against GnuTLS 2.x makes luxid work as 
expected. If you can try any of these and confirm, it would be great!

Unfortunately I have not managed to obtain a sane backtrace from luxid 
to pinpoint the exact cause of the crash. I'll do a little more research 
and reassign this bug to either curl, or gnutls.

Apollon
