I confirm this crash with H263-1998 and ekiga 3.2.6.  100% reproducible
by just putting this codec the first one, and calling 500 ekiga net 

It seems to me that it is in libavcodec:
Thread 24 (Thread 0x7fffd4d34950 (LWP 12579)):
#0  0x00007fffe6062f79 in ?? () from /usr/lib64/
#1  0x00007fffe5e7cfd1 in ff_epzs_motion_search () from
#2  0x00007fffe5e92ea5 in ff_estimate_p_frame_motion () from
#3  0x00007fffe5e1ad5e in ?? () from /usr/lib64/

I looked at the source of ffmpeg, and ff_epzs_motion_search is a 50-line
function with many computes, so difficult to see where precisely the
crash happens.
