I remember having problems with Qt as soon as I started defining
QWS_KEYBOARD, but I don't remember if the problem was exactly the one
you had.

Can you try to add the attached patch to the Qt package? It has been
written for Qt 4.7.3, but since the patch is trivial, I guess it can be
quickly adapted to Qt 4.8.2. It's the patch I had to fix the problem I
encountered, but again I don't remember the exact problem, and I have
been apparently too lazy to describe it in the patch description.

Best regards,

Thomas
