Review request for KDE Base Apps.


Description
-------

The attached patch is an attempt to prevent access of a NULL m_combo variable whenever the user removes the location toolbar. Since the location toolbar is the parent of m_combo, its deletion means the the deletion of m_combo as well.


This addresses bug 172692.
