X Server can't find font `fixed'

[Michael Abraham Shulman <shulman@caltech.edu>]

Hi,

I just upgraded a bunch of packages to unstable and now my X server
dies saying

Fatal server error:
could not open default font 'fixed'

I don't even know what package this problem is in.  I tried downgrading
xserver-common, xfs, and xserver-svga, but that didn't fix the problem.
Can anyone suggest where the problem is?  I can send more detailed info
but I don't know what is relevant.

xserver-common: 3.3.6-11
xserver-svga: 3.3.6-11
xfs: 3.3.6-11

Thanks,
Mike
