Tested with RHL 8.0 and using sv_SE.UTF-8. The message "%d Megabytes" doesn't show up translated (see the screenshot in https://bugzilla.redhat.com/bugzilla/showattachment.cgi?attach_id=79717). In Swedish it should be "%d megabyte" (lowercase M and no s).
Fixed in CVS
Long fixed, RH 8 not supported, and magicdev and s-c-p aren't shipped anymore. (Pirut replaced s-c-p.) Closing.
