I am no expert, but this looks like the segmentation fault happens in
`libavutil.so.51` or `libc.so.6`.

Could you please paste the output of the following command.

    $ dpkg -l libavcodec53 libavutil51 libc6

Are you able to reproduce this error? If yes please run Ekiga under the
GNU Debugger and do `aptitude install libc6-dbg libav-dbg gdb`
beforehand [1].

        gdb -- args ekiga -d 4 2>&1|tee log_$(date +"%Y%m%d-%H%M%S").txt

Upstream in the GNOME Bugzilla bug tracking system, I created ticket
#683668 [2]. It would be great if you could subscribe to that report and
also add further information there.


Thanks,

Paul
