Comment 21 for bug 723458

Gytis, I it so great that you are here.

I do not have any proof, but given that the bad commit in gtk c282958fb4bb25c736c682735002d15c50cb44d0 realy just is an optimization, the usage of the affected funtion must be somewhat wrong - or at least missunderstood.

All other gtk-applications just as fine after as before the change. The change is quite small.
