Insight
A misconfiguration in the default application priorities was causing file-roller (an archive manager) to be used by default for ISO image files, instead of nautilus-cd-burner, for the GNOME desktop environment. This bug has been fixed with an updated shared-mime-info package, which also contains additional file types.
Affected
shared-mime-info on Mandriva Linux 2007.1,
