QPainter strange warning

[mchara]

Hi,
i'm using QPainter in my paintEvent(together with QStylePainter), and i get warning like this:

Warning: QPainter::begin: Paint device returned engine == 0, type: 2

I can't figure out when exactly this happens and it's rather hard to reproduce it. type 2 is something like QuickDraw on MacOS but i'm working on windows xp, so i'm totally confused...

Does anyone know what's this warning about?

Hmm, what does this actually mean? Notice that QStylePainter is a QPainter. Do you actually have two painters on the same device at time?
