OK, so patch is mostly correct. The bigger issue is that enabling spaces also screws up the db uri parser. I'll start working on a patch for that.

Plus note that itertools is riddled with memory issues, try to avoid it (ok, for the tests it's fine).

See what I get for writing tests? :)

Test fixed in [9229]
