pyqt applications won't run in oneiric beta 1

[Stephen G]

I have been unable to run pyqt apps such as eric4 in oneiric beta 1. I get a lot of error messages such as:
(python:3489): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed
and python also rapidly consumes the entire systems memory making the entire desktop unstable.

What version of Qt do you have?

[Stephen G (stephen.g)]

libqt4-core is 4.7.4-0ubuntu1
note that I've marked this bug as a duplicate of #805303 and am able to work around it by using qtconfig to change the style away from the default (gtk+)
