[CentOS] system-config-users error

Has anyone seen this error before in CentOS 4.2? I've been setting up 
two identical systems, one has this error and the other doesn't.  Short 
of removing and re-installing all the packages related to gtk is there 
an easier solution? I have removed and re-installed all the 
system-config tools, but the error didn't change. 

sudo system-config-users
