I installed the usermode-1.28-2.i386.rpm that I found on a Red Hat update mirror today. That file includes some translations, including my Swedish translation: /usr/share/locale/cs/LC_MESSAGES/usermode.mo /usr/share/locale/hu/LC_MESSAGES/usermode.mo /usr/share/locale/is/LC_MESSAGES/usermode.mo /usr/share/locale/no/LC_MESSAGES/usermode.mo /usr/share/locale/sv/LC_MESSAGES/usermode.mo I couldn't get my Swedish translation (sv) to work with either of the programs, although I tested with both LC_ALL=sv_SE and LC_ALL=sv. Are the translations not enabled?
Fixed in 1.29. Since the previous version wasn't even translated, we'll just tag it as fixed in Raw Hide.
