[MPlayer-users] Segfault with -vf scale and -brightness/-contrast/-hue/-saturation

I just run into this problem recently, I had an apparently broken video
clip which looked about like 4:3 picture streched to fill a 16:9 display,
but on my 4:3 monitor. So I thought I could use the software scaler to
fix it while viewing. But no, it segfaulted every time. Turns out it
was caused by having brightness=10 and contrast=10 in my config file. It
seems that setting any of these attributes on command line or in config
file causes the segfault. Any file, any vo, sound/no sound, doesn't
seem to matter. Version is up to date CVS.
