Since KDE has been added, there's been the unfortunate side-effect of 
some KDE programs running in GNOME undesireably. (Eg: double-clicking a 
pdf file launches kpdf instead of gpdf.)

Links (Skip ahead for a summary):

To summarize:
1. Gnome uses /usr/share/applications/defaults.list to pick programs to 
run, and in its absence picks seemingly randomly, causing KDE programs 
to be run sometimes instead.
2. KDE uses InitialPreference, an entry in the .desktop files, to 
determine the file association, the highest number entry in all the 
.desktop files gets the program

Currently, without a defaults.list file, gnome is essentially picking at 
random what to use in association with a file when double-clicked, be it 
kde or gnome programs.  Now, with a defaults.list file, it's possible to 
tell gnome where to go for different file types.  As KDE uses a 
different system(and will until/if freedesktop.org adopts defaults.list 
as a standard), it would appear, to me at least, that the best course of 
action is to create a standard defaults.list that uses all gnome 
applications, and drop that in a package that's grouped with gnome.

I've tested this on my system, and to my pleasure, I now have gnome 
running just gnome apps, and kde running being itself. hehe.

I've started a defaults.list that I've attached to this e-mail... I 
think we should look at this carefully... Slide this into 
/usr/share/applications and things should work.

The downside, depending on how you look at it, is that if you are 
running Gnome, and click on a file that has no association you might end 
up with a KDE application running.  If there are no associated GNOME 
apps at all, but there are KDE apps, you will definately  have a KDE app 
run.  (Vice-Versa also applies.)
