Tested with beta4 and LC_ALL="sv_SE" and LANG="sv_SE" and all RHN updates as of
this moment.

When I click on the "User Manager" icon in the Start Here->System Settings and
subsequently enter my root password, I get a User Manager window, but all
messages in the interface that should contain Swedish characters appears
truncated at the position of the first Swedish character. This results in a lot
of truncated messages in the interface, their meaning being barely readable and
guessable.

Please see the attached screen shot.
