Bug#505965: closed by Debian Qt/KDE Maintainers <firstname.lastname@example.org> (Bug#505965: fixed in kdepimlibs 4:4.4.1-1)
We believe that the bug you reported is fixed in the latest version of
kdepimlibs, which is due to be installed in the Debian FTP archive:
By looking at the upstream revision, it is quite obvious that this does
not fix the bug. The erroneous holiday file has just been renamed to
holiday_de-by_de. I have no opportunity to test this, but I would expect
that the wrong holiday would show up when selecting that holiday region.
Should I better report this upstream?
