--- Comment #2 from Steven Dorigotti <s.dorigotti at endian.com> ---
I can confirm both the bug and the solution provided by Paul Sturm. It doesn't seem to have noticeable side effects.


ps: this is the patch I apply to Qt 4.8.6:

     m_ownerPopup.m_popupVisible = false;

     emit m_ownerPopup.didHide();
