Debian apt-get blues

I seem to have broken something with Debian by trying (foolishly) to
uninstall wdm while in X. Now I get:

--- cut here --- cut here ---
# apt-get remove wdm
Reading Package Lists... Done
Building Dependency Tree... Done
The following packages will be REMOVED:
wdm
0 packages upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

Removing wdm ...

Installing is no better:

Sorry, wdm is already the newest version.

So now kdm is broken to boot. I'm in a bit of a quandry, and I would
like to get a graphical login going again. Any suggestions? I've tried
"dpkg-reconfigure wdm", "apt-get --fix-missing wdm" and screaming at
it, but no luck so far.

Thanks,
