I've installed the linphone-dbg package and started linphone through gdb. 
The only additional info I get is this:

   Program received signal SIGSEGV, Segmentation fault.
   0x00007ffff1d5b1f5 in av_log () from /usr/lib/x86_64-linux-gnu/libavutil.so.51

Seeing that it segfaults in libavutil it needs to be said, that I'm using 
Christian Marillat's libavutil from deb-multimedia.org. 
deb-multimedia.org/wheezy is in my apt sources, so whatever is present 
there overrides Debian's own packages and gets installed instead.

What I did next is to step through linphone in gdb. I can get to line 1765 
in main.c (the line number is what gdb is showing me). If I say "step" at 
that line, the program segfaults.
