Description:
A geometry field with a spatial index returns ERROR 1105 (HY000): Unknown error when inserting a default value or other invalid value instead of a more helpful error message.

How to repeat:
mysql> CREATE TABLE geom (foo GEOMETRY NOT NULL, SPATIAL INDEX(foo) );
Query OK, 0 rows affected (0.02 sec)

mysql> INSERT INTO geom (foo) VALUES (NULL);
ERROR 1048 (23000): Column 'foo' cannot be null

mysql> INSERT INTO geom (foo) VALUES (1);
ERROR 1416 (22003): Cannot get geometry object from data you send to the GEOMETRY field

mysql> INSERT INTO geom (foo) VALUES ('x');
ERROR 1416 (22003): Cannot get geometry object from data you send to the GEOMETRY field

mysql> INSERT INTO geom () VALUES ();
ERROR 1105 (HY000): Unknown error

mysql> INSERT INTO geom (foo) VALUES ('');
ERROR 1105 (HY000): Unknown error

Suggested fix:
All insert statements are correctly dismissed as errors. 

The first three error messages are fine and make sense as we have the NOT NULL constraint (as required by the spatial index) and we can't insert values directly.

But the last two error messages aren't quite clear ("Unknown error") and should be changed.

Thank you for a bug report. Verified just as described with 5.0.25-BK on Linux:

openxs@suse:~/dbs/5.0> bin/mysql -uroot test
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mys
ql.sock' (2)

You can turn off this feature to get a quicker startup with -A

ERROR 1416 (22003): Cannot get geometry object from data you send to the GEOMETRY field
mysql> INSERT INTO geom (foo) VALUES ('');
ERROR 1105 (HY000): Unknown error

This "Unknown" error message is a bug.

  We issued UNKNOWN ERROR initially in this place and forgot to
  fix it when we implemented informative error message for this

The patch "bk commit into 5.0 tree (holyfoot:1.2293) BUG#21790" is ok to push.

Noted in 5.0.32, 5.1.14 changelogs.

Inserting a default or invalid value into a spatial column could fail
with Unknown error rather than a more appropriate error.
