gitk fails to start after upgrading to 2.6.3 (cannot load translation)

Hi!

After upgrading Git to 2.6.3 (from 2.5.0), gitk refuses to start when trying to load the Swedish translation if I pass it a commit range:

   $ gitk v2.5.0..v2.6.3
   Error in startup script: bad menu entry index "Ändra vy..."
       while executing
   ".bar.view entryconf [mca "Edit view..."] -state normal"
       invoked from within
"if {$cmdline_files ne {} || $revtreeargs ne {} || $revtreeargscmd ne {}} {
     # create a view for the files/dirs specified on the command line
     se..."
     (file "/usr/local/bin/gitk" line 12442)

If I start it without any parameters, it does start up, but the main menu is untranslated.

The translation for this entry is defined in gitk-git/po/sv.po line 135 and hasn't changed since 2008, even if the sv.po file does have a few updates since the previous version in some other places.
