XmString item;
XtVaGetValues( combobox, XmNselectedItem, &item, NULL );

/* you must free this when you are done with it */
XmStringFree( item );

XmNselectedItem is an XmString, not a string. To convert it to a string,
you need to use one or more of of the XmStringGet... functions. Try
char *str;
XmString item;
XtVaGetValues( combobox, XmNselectedItem, &item, NULL );
XmStringGetLtoR( item, XmFONTLIST_DEFAULT_TAG, &str );
XmStringFree(item);

/* ... and you will also have to free the string eventually: */
XtFree( str ) ;
