It usually takes me <15 minutes, but arguably I know 
what to do.
As said, I can help you.

I may misunderstand: Is the crash only reproducible 
with xbmc and not with FFmpeg?
If yes, the bisect will probably not help because 
the reason is something like a unsufficiently aligned 
buffer within xbmc.
If the crash is reproducible with FFmpeg, you don't 
need xbmc to test.

The optimal version to start is of course the one 
you know is working fine (if I suggested one "in 
the middle" it would not save you more than one 

If you know that 0.10.2 is working, you could 
start with 3c5fe5b (that will save you one
