[Development] Cherry pick fix from Qt5 to Qt 4.8.x

[Thiago A. Corrêa]

Hi,

    I've sent a patch to Qt5 that's already integrated, and I would
like to cherry pick it for qt 4.8. I haven't found the process
documented anywhere, could someone point me in the right direction?
    I must say I'm not very good with Git, so the more details the
better. Appreciate the help.

Kind Regards,
     Thiago A. Correa
