The removal of "data/" was intentional, because it prevented accessing other 
things under local/share. It was a hardcoded subdir that had no reason to be 
there (check local/share, the xdg standard is to put stuff directly in there, 
not in a data subdir).

However I didn't anticipate the migration problem, indeed.

At this point changing the behavior of QStandardPaths::DataLocation would 
surely create even more trouble, so instead I can offer a
 QStandardPaths::Qt4DataLocation which would have the "data", for easier 
migration from Qt4. How does this sound?

writableLocation() is a more direct equivalent of 
QDesktopServices::storageLocation btw.

Yes, thanks. I get too much email to be able to monitor the development at qt 
list :(

Yes.
