crash on data view if other person adds column to table

create table

CREATE TABLE `test` (
    `col1` INT(11) NULL DEFAULT NULL
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM
;

go to the datagrid view of the table on your computer

open heidisql on a second computer and add there a column to the table

ALTER TABLE `test`
    ADD COLUMN `col2` INT(11) NULL DEFAULT NULL AFTER `col1`;

on you computer in the datagrid try to change value in col1 ... curious error message press multiple times f5 to refresh ... crash

mysql: 5.0.51

heidisql: 9.3.0.5083

on you computer in the datagrid try to change value in col1 ... curious error message press multiple times f5 to refresh ... crash

sorry can't edit message, quoted line should be 2 lines

on your computer in the datagrid try to change value in col1 ... curious error message

(then) if you press multiple times f5 to refresh ... crash

• no need for 2. computer, 2. instance of heidi is enough (not only a 2. connection!)
• no need to edit col1, crashes also with refresh (f5) only
