Re: core dump when parsed VoIP call with text media

[Jaap Keuter <jaap.keuter () xs4all nl>]

Tried it with current HEAD of master, still same event happens. Packet number seems to be 1, but packet scope assert 
fails. 
This will need a deeper look, so please file a bug report with relevant files attached so someone with time available 
can take a crack at it.

Thanks,
Jaap
