In particular /usr/share/mimelnk/image/x-image-raw.desktop is in kdegraphics-3.5.x, so including it here will cause conflicts. See also (upstream): http://bugs.kde.org/121242
Ack, per -devel mailing list, looks like koffice includes it too.
I will exclude x-raw.desktop file from devel branch, and for FC4 branch I'll provide patch that will clean up "Patterns" (in FC4 KDE >= 3.5 is available only in updates).
You really should exclude the .desktop file from FC4 too, since the conflict will arrise there too when/if anyone installs/updates to kdegraphics-3.5.x from updates.
I've excluded x-raw.desktop from FC4 and devel.
