File-roller, in Quantal at least, is experiencing a lot of failures right now. There's a pretty good chance that's the problem. What do you see if you run file-roller from the command-line?
If it fails, the bug would likely be a duplicate of bug 1035688, or one of these crashes: https://bugs.launchpad.net/ubuntu/+source/file- roller/+bugs?field.searchtext=crash&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=&orderby=-id&start=0 Sorry for the ugly link, it's just searching file-roller bugs for 'crash'. What versions of (x)ubuntu and file-roller are you running? I'm going to mark this incomplete until there's more information.
