Other information:
I'm using gstreamer Debian package which not compiled with debugging symbol enabled. 
So i'm not sure the trace is very useful. Moreover, the bug not not appear when one specifies 
the framerate: 
gst-launch-0.8 -v videotestsrc  ! video/x-raw-rgb,framerate=25 ! ffenc_mpeg1video !  fakesink

Comment 1 Ronald Bultje 2005-05-18 10:11:01 UTC

They accept fps [ 0, .. ] instead of [ 0.0000000000000000001, .. ]. We generally
use 1 as minimum. Someone needs to go over all of them and so s/0/1/ or think of
another 'starting from, but excluding' in caps statements.

current cvs:

luogni@bucefalo:~$ gst-launch-0.8 videotestsrc  ! ffmpegcolorspace !
ffenc_mpeg1video !  fakesink
ERROR (0x80508f0 - 310882:15:16.096084000)          ffmpeg(25724) (0):: only

ERRORE: la pipeline non vuole riprodurre.

so it doesn't crash anymore..

Good enough.
