[MPlayer-dev-eng] [BUG] sig11 again in reading a JPEG file

[Gabucino]

The file is displayed, but then MPlayer dies with sig11. It also doesn't work
with -vo null, -vc ijpg, etc.
However it does work with '-vop disable' i.e. not using -vop pp (on by default
in my config file)

AFAIR this should be already fixed, shouldn't it?
