[SFLphone] seg faults

Tue Sep 1 15:48:19 EDT 2009

We knew about this kind of bug for quite some time now. 
The more I see it, the more I think that it comes from invalid data
being passed to the Dbus-c++ binding. When SIGPIPE is thrown, it's most
likely because the other end (a glib binding for example) closed the
dbus socket because it received something that it shouldn't have. 

Good to see that the bug appears similar to the one Maxime Chambreuil
was experiencing.
