Dia Won't Save files anymore

[Jeff Hornsberger <jhornsbe@csc.uvic.ca>]

Hi. I'm not sure if anyone else has had this problem, but for some 
reason my Dia won't save valid Dia files anymore. It can open my old Dia 
files, but when I try to create a new one and save it it gives the 
message: "xmlNewGlobalNs() deprecated function reached". Then when I try 
to reopen that file later it says that it isn't a valid Dia file. Has 
anyone else experienced this or have a solution for this? Thanks. -Jeff
