That sucks, because I don't. Maybe a 4.5 vs 4.6 issue? Could you look into
the qenums code and try to catch where it is reporting an empty string for
an enum name? If you need help finding your way through the code, just let
me know.

Thanks for doing all the grunt work testing here. Sorry I have not been
taking the time to test things. Hopefully the demo directory will come to
represent a nice set of tests. Also, Qt itself has tests which we could
translate to R.
