The ComboBoxEntry is trying to set the text of the entry from the item you
selected, but that text is NULL.  See below.

This means the error is occurring deep in the library, usually as a result of
you setting something up incorrectly.  :-/

This is unnecessary -- ComboBoxEntry sets up a text renderer by default (or at
least it did in my test code).

         # tell the ComboBoxEntry which column of the model contains
         # the text to display in the Entry.
         $cmbJobName->set_text_column (0);
