Actually file-roller works fine,but I did update on default 7.1 not there then I tried untested not there.I just finished installing 7.1RC4. Looks good. You did say you are using RC4,32 or 64? When I booted install it said you have booted VLocity64. I know I downloaded 7.1RC4 STD. For 64 bit on 32 bit machine works good because that is what I'm using. I'll look again at repositories for file-roller. Xarchiver error check output.
