I wonder whether this is necessary (I have to say that I am not the 
person who wrote the RPM spec file)?  My thinking is as follows: since 
those directories are created (but their ownership not claimed) by our 
spec file, they - and the files in them - should be created when the RPM 
is installed if they do not already exist, without causing problems if 
the packages claiming ownership are installed later.  However, the only 
situation in which shared-mime-info and hicolor-icon-theme are likely 
not to be installed is if no complete desktop environment is installed. 
  In this case the files we install into those directories are harmless 
but useless, and as long as there isn't a consumer for them, pulling in 
shared-mime-info and hicolor-icon-theme will not make them any more 
useful, so we don't really gain anything from depending on those 
packages.  What is more, if we did try to pull them in we would
have to check whether the package names are the same in all RPM-based
distributions which we support and if not hack our spec file to do the
right thing.

Regards,

Michael
