All of a sudden -vo png option crashes the mplayer

[ramapal6@…]

I have been using the option mplayer -vo png:z=0 for some time. But yesterday it crashed and from that point, the -vo png or jpeg driver continuously crashes the mplayer. I am using kubuntu 8.04. The error I get is :

MPlayer interrupted by signal 6 in module: filter_video
