I tried again with the development version listed above. Unfortunately I got 
the following result:

Could you let me know which version of avifile works for you ? I had been using 
a cvs version, but
if necessary I could downgrade to a release version.

I guess I've just turned up a new problem :) I think there is some problem in 
the development
version of swftools, because with my avifile library being exactly the same and 
using swftools
version 0.4.4 there is no segfault when trying to convert. Also, the exact same 
avi can be played
by mplayer and aviplay.
