KLibido - KDE Linux Binaries Downloader

When downloading a nzb file from a browser such as Firefox, and selecting
KLibido as the application of choice to open it with from inside Firefox,
KLibido starts and add rightly adds the files the nzb points to into its
queue.

However, if KLibido is already running, rather than adding the new nzb data
to the existing klibido application and putting these extra files into the
queue, it will start another klibido application and add it to that queue
instead. This introduces problems as the two klibido applications now
running compete with eachother for the same usenet server, resulting in
disconnection by the server on one or both of the applications, as well as
wasting resources, and causing other buggy behavior since it's not meant to
be run that way.

I first filed this at the bugs.kde.org tracker and they told me it's not a
KDE problem but a klibido problem and that I should post it here, so here
ya go.
