Comment (by RJVB):

 So... `pre-activate` is indeed not reliable for me, it seems need a
 preceding install event. But post-deactivate does work every time.

 That means there will need to be a launchd agent or daemon similar to what
 KDE4 does with kbuildsycoca4, which watches $prefix/share/mime/packages .
 Without that, activating a different version of shared-mime-database would
 leave you without the cached info.

 The question now is what has to be deleted. Obviously I cannot just remove
 all of $prefix/share/mime, but is there anything other than
 $prefix/share/mime/packages that needs to remain?
