Title:
  Picard freezes X when overlay scrollbars are enabled

Status in overlay-scrollbar:
  Confirmed
Status in overlay-scrollbar package in Ubuntu:
  Confirmed
Status in python-qt4 package in Ubuntu:
  Confirmed

Bug description:
  after starting a wireframe shows up, and then a high I/O-load occurs, memory is consumed up to 90%, X-Windows gets completely unusable (freezes), but changing to console (ctrl-alt-f1) is possible - 20-40s after pressing the keys - and instantly I/O-load drops to zero as switching to console happens.
  Therefore I think this may be a problem with QT or even X-Windows itself.
  There are some errors printed by picard/QT/X-Windows on the running terminal:
  (python:5103): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed
  {Comment: dozens of that}
  QWidget::setMinimumSize: (/MainWindow) The largest allowed size is (16777215,16777215)
  {Comment: some of that}
  QNativeImage: Unable to attach to shared memory segment.

  {Comment: these are the last lines of the log - after that everything freezes}
