Okay. I am not good in reading backtraces, but there are a lot of
"empty" lines which I tried to fill. But: these lines are not from
hylafax itself. (btw: hylafax or capi4hylafax? c2faxsend/recv are
from capi4hylafax...)

*nod* but even with non-stripped c2faxsend there is no information
about that.
I tried to send a fax to myself and in that way I got a coredump for
c2faxsend. Seems to be the same problem (also mentioned from other
people). The backtrace is as the following:
