Code review comment for lp://qastaging/~kamstrup/unity-lens-applications/ratings-query

Looks nice! I didn't check out the SC branch, so didn't test it fully, but at least I tested the db-not-there case.

Just a couple minor things:

455 + public Database () throws GLib.IOError;
you're throwing GFileError, so either "throws FileError" or just "throws Error".

180 + ratings.query (pkginfo.package_name, out result);
perhaps it'd better to enclose it in an "if" considering it returns bool

362 + out_result->pkgname = pkgname;
a bit dangerous, but as long as it's not really used...

But all in all, approve! :)
