You shouldn't have a mapdevfs binary installed at all; this isn't really os-prober's fault (it can deal with a *missing* mapdevfs, but not a broken one), but the fault of whatever set your system up to have a mapdevfs binary without its dependencies satisfied. Could you please attach /var/log/installer/syslog to this bug?
