 Replying to [comment:5 hamish]:
 > We may not be able to add the requested functionality for the next
 release, but can we do anything about replacing the segfault with a
 G_fatal_error()?

 The following is based upon the backtrace, and is completely untested:

 {{{
 --- lib/db/dbmi_client/select.c (revision 40258)
 +++ lib/db/dbmi_client/select.c (working copy)
 @@ -134,6 +134,8 @@

      table = db_get_cursor_table(&cursor);
      column = db_get_table_column(table, 0);    /* first column */
 +    if (!column)
 +       G_fatal_error(_("Table has no columns"));
      value = db_get_column_value(column);
      type = db_get_column_sqltype(column);
      type = db_sqltype_to_Ctype(type);
