Now that you've found a work-around to setting the combo-box insensitive,
could you please also ensure that there is a bug filed for GtkComboBox ?

As far as I know, widgets in GTK+ are supposed to maintain their state
when insensitive (for instance, an insensitive GtkSwitch, GtkLabel,
GtkEntry, GtkToggleButton, GtkRadioButton... all can be set insensitive
without losing the current state).

I don't see why it would be acceptable that the GtkComboBox behave
differently than other widgets regarding sensitivity, and not filing a bug
about it is an open invitation for the bug to remain unfixed.

Thanks,
