A few internationalized format strings have only one %s in the default
while two strings are being passed. Change those defaults to have two
%s's, which means we also have to update the .po files to match. May as
well throw in the extra %s in the translated version while we're at it.
- Some .po file fixes (Mike FABIAN <mfabian@suse.de>)
- Fixed the problem with the root menu code changing the locale setting as
a side effect of loading a localized menu
- Fixed e memory leak in the code that reads a localized root menu
