VideoWidget::snapshot() doesn't work

[jarosda]

Hi all,
I'd like to ask you if someone use method
@QImage Phonon::VideoWidget::snapshot()@

I tried to use it but with no success. I get just black picture. I read some threads about it and they point to possible phonons bug.
Could someone write if this methods works for him and if yes on what version of qt and phonon? Thanks in advance.
