I ran into this as well after using a bbappend to disable a number of
Qt features, including the building of demos that get staged in the
aforementioned path.  In my case, that qtopia directory (and any
subdirectories) wound up either being empty or containing files that
were unnecessary for my build.

My quick and dirty solution was to just to add a install_append()
containing a 'rm -rf ${D}${datadir}/qtopia' in my bbappend. (Be sure
you don't have anything important in there!) I'd be curious to hear if
there's a better approach to this as well...
