asf2divX.txt : this file

I have a problem to deal with somes ASF encoded files. I'm trying to 
transform these files to AVI files using 2 (or 3) pass MPEG-4 encoding. The 
aims is to be able to merge then after using avimerge.
The problem is that mencoder segfaults on certains files at the begining of 
the last pass. As proposed on MPlayer-users list I've prepared a bugreport.

Here is my config :
