Some hunks of the patch also seem flawed, e.g.:

@@ -1258,7 +1261,9 @@ const QList< QList < int > > & 
KateCompletionModel::columnMerges( ) const
 void KateCompletionModel::setColumnMerges( const QList< QList < int > > & 
columnMerges )
 {
   m_columnMerges = columnMerges;
-  reset();
+
+  beginResetModel();
+  endResetModel();
 }

(the call to beginResetModel() should be the very first statement in this 
block).

Anyway, I'll try to finish up my patch so we can possibly revert 
e6374518f5a966b8badda3a5e90fb873cd7ec08e and re-apply the diff from the 
review-request.
