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.
