I tried to reproduce the problem with a self compiled Qt 4.7.2, but it still
works fine, and the valgrind report shows only some erors like the attached.
I don't believe that they are related, but one never knows.
Can you rerun valgrind with
--track-origins=yes
? That should give us a hint where the initialization is missing in your
case.
