--- Comment #11 from Rafał Mużyło galtgendo@o2.pl --- The message itself isn't, but there also a function, that definitely is implemented, is reported as missing due to using delayed load mechanism.
As for being a nag, I only do that if I receive no valid feedback *and* I'm nearly sure I have a good point. In that particular case, the bug is over 6 months old *and* that first patch almost certainly does what the API docs tell it's supposed to do (as a random bonus, the main part of that particular bug - unrelated to the patches - is about dying due to excessive memory consumption by graphics).
