> 1. Launch designer-qt4, create a dialog with buttons bottom. Press
> Ctrl-R to preview the dialog. You should see a normal dialog with

> 2. Launch "plugins.py" from PyQt4-devel-4.4.4/examples/designer/plugins
> 3. Create a dialog with buttons bottom. Press Ctrl-R to preview the

> 4. Close the preview, select the buttonBox, find standardButtons in

Should be fixed in tonight's PyQt snapshot - or at least worked around as
I'm still not sure if it is a bug in Designer or I'm mis-using the
PyQt registers QDialogButtonBox::StandardButtons (which is a flag type) as
a meta-type. Unregistering it fixes the problem.
