Seems this was it: 
http://git.videolan.org/?p=ffmpeg.git;a=commit;h=737aa902f069ed218fd2d13c59015391facf73c8 
and affects only MPEG/DVD for some weird reason. It seems -noslices can 
fix some MPEG/DVDs but some just give 'signal 11 in module: 
filter_video' (instead of decode_video) with the same unable to do a 
backtrace.
