I was able to reproduce the crash, (in good scientific style).  An app I have
called KRunBox, uses a QComboBox for command entry.  If I remove the QComboBox
and place an editable KComboBox instead, the app crashes start away on the
mouse entering the KComboBox.

Testing it was not my code causing the problem, I just created a new project,
created a new QTDesigner form, placed a KComboBox on the form, inherited it
from the main widget and ran it.

It crashed both in QTDesinger (in form preview) AND when the app was run on it 
own.

I have included some details below if you need them.

Thanks

Paul.
