Creating a desktop file alike:

[Desktop Entry]
Name=sthg
Exec=sthg %u
Terminal=0
Type=Application
Encoding=UTF-8
Categories=Application;sthg;
MimeType=some-mime-type
InitialPreference=X

Where X > preference for the original app handling "some-mime-type"

then running desktop-file-install

shall do it for KDE, although I'm not sure that would work
for GNOME (well application will be added to menus/list of handlers
for given mime-type but I'm not sure whether InitialPreference
key will be taken into account ..)
