[PyQt] QMainWindow bug?

[Erik Janssens]

there was a change in sip/pyqt from 4.8.1 to 4.8.2 regarding
the detection of objects deleted by qt but still referenced in
python (which is the case here).  in 4.8.1 sip/pyqt tried to
detect this to avoid segfaults.  this detection however brought
other issues with it, therefor the detection was turned off again
in 4.8.2

the solution is not to keep references in python of objects
owned by qt when they might get deleted.
