Comment (by nixscripter):

 I thought the log was too long to post outsize the zip file, but after
 specifically counting, 93 is less than 100. Likewise, I thought that
 release candidates were supposed to get their own testing separate from
 the current head. I will remember both for the future.

 The git version works:

 $ ffmpeg -v 9 -loglevel 99 -f x11grab -s 128x80 -r 25 -i :0.0 -b 1200k

 So I suppose this means your release canditate needs to move up a little.

 More information:
 Arch Linux i686
 X server version 1.10.2

 Unfortunately, I don't know what library the x11grab uses. Anything else
 needed, just ask.
