Bug#254951: Reproducing bug #254951

[Oliver Korpilla <okorpil@fh-landshut.de>]

Hello!

I've seen the following strange occurence in ~/.kde/share/config/kickerrc after
trying to reproduce your "special" behaviour for mozilla-firefox:

[ServiceButton_4]
DesktopFile=/var/lib/menu-xdg/applications/menu-xdg/wterm.desktop
FreeSpace=0
StorageId=wterm.desktop

[ServiceButton_5]
DesktopFile=/usr/share/applications/mozilla-firefox.desktop
FreeSpace=0
StorageId=:mozilla-firefox.desktop

[ServiceButton_6]
DesktopFile=/usr/share/applications/mozilla-thunderbird.desktop
FreeSpace=0
StorageId=mozilla-thunderbird.desktop

Note, that after the changes took effect and the session was saved,
:mozilla-firefox.desktop was put there instead of mozilla-firefox.desktop, same
goes for mozilla-thunderbird.desktop, if you change that. If you edit that file 
and exit KDE, contents will be the same on startup (so Kicker stores it kickerrc 
when you go down).

/var/lib/menu-xdg/applications/menu-xdg/ is treated differently in this respect 
than /usr/share/applications (where a lot of the KDE apps reside, too).

There seem to be no obvious reason, because both the .desktop files in the dirs 
have the same permissions and owner: root.root with -rw-r--r--.

With kind regards,
Oliver Korpilla
