Looks like you're crashing because UT3 can't load a custom character ( http://www.filefront.com/12880804/rscrusader_v1.zip/ ).  No idea what servers you've tried but most servers should crash UT3 if this is what the problem is?  We don't have this character installed on our server- and I can't find any packages that require these files.  We do allow custom characters but it shouldn't crash your game if someone is using that character?

A character defined in UTCustomChar.ini has missing files.  So you either need to install it (download link above) or remove the lines in UTCustomChar.ini and remove the files.  The lines are probably layed out like this:
