traceback error

I have a test machine that I am setting up to be an up2date server. 
Currently, I am testing it on my desktop, and I'm getting a traceback 
error on the client machine.  I have tried to re-install up2date from 
the rpm, but the error still persists.  In the FAQ's, it says a 
traceback error is due most likely to the clocks being out of sync.  I 
used rdate on the same server to get the clocks exactly the same.  The 
error is posted at the bottom.  I can / up2date -l/, or /up2date 
--showall/ fine, but when I try /up2date -u/, or the graphical up2date, 
I get the error.  I am running current-1.0.3 on RedHat 7.3.  Any ideas?
