The "drakrpm" program crashed. Drakbug-16.104 caught it.

Selected libuser-python 64 bit archetecture for install. This problem started AFTER I had installed 
other programs - I don't believe that the libuser package is at fault, but rather, some package that's already installed having a malformed description causing problems in the RPM database. The error above shows up 
with many different packages, and each of them give the error as soon as they are selected. 
Also, I can install them with urpme just fine. 
I know this is a duplicate, but it seems the problem may be in some commonly installed RPM that doesn't get installed as part of the normal desktop setup. I've installed mostly games and python modules since the initial install.
