Hi Konrad

I see you ran gdb on that coredump. Could you give us a little bit more,
using "bt full". The function sccp_channel_updateChannelCapability is
called a lot in our sources, so we need to know where it was called
from.

after the bt_full please also enter:
print channel
print c

Regards,

Diederik
