Thank you both for reporting and confirming this bug. According to the upstream comment
"GtkSpell doesn't provide a way for us to distinguish when no dictionary is found. We can keep this ticket open, but there isn't a whole lot we can do about it."
it seems clear that this is a Wishlist bug since the functionality isn't actually there to begin with (to detect when dictionaries aren't present). I will mark it as so.
