Getting segmentation faults with glxinfo, mplayer and others

[Rico Secada <coolzone@it.dk>]

Hi.

I am running Debian stable.

Suddenly when I run mplayer, xine, xmms, glxinfo and other I get
segmentation fault.

I have tried running both with and with Nvidia drivers.

I have run a memtest without any errors.

What can be causing this?

Best regards.

Rico.
