Hi, you may or may not remember this mail from myself 
It spoke about the problem some applications have regarding specifying the
MimeType entry due to it beign based on the available plugins for that
Almost nobody commented on that mail so i went straight ahead and coded a
solution for KDE, and the solution was MUCH easier than i though. If you want
to see the current patch see 
I copy here the important information about the structure
Virtual mimetypes are directed towards applications that use plugins
and the mimetypes they support depend on the installed plugins.
To make an Application use the virtual mimetype system, put
in its .desktop file
Then each plugin has to install a .desktop file like this
MimeType=mimetypes this plugins adds support for
I am writing this mail here to see if we can agree that this is a good and
easy way to do it (i coded the patch in 4 hours without having any knowledge
of how that worked on KDE so it can't be that difficult on other DEs)
Basically i would want the .desktop spec to mention the Virtual-MimeType=
entry beign a ; separated list of mimetypes that should be added to
each .desktop file that cotains that virtual mimetype in the MimeType entry.
