Bug #233 Spatial index on non GIS-Data

Description:
Strange behaviour (segfault) when adding a spatial index to a column which 
contains garbage.

There are some more segfaults, but I guess they have the same reason. (if not 
I'll report them later).

How to repeat:
mysql> create table gis_8 (a geometry not null);
Query OK, 0 rows affected (0.00 sec)

mysql> insert into gis_8 values (GeomFromText('Point(1 2)'));
Query OK, 1 row affected (0.00 sec)

mysql> insert into gis_8 values ('Garbage');
Query OK, 1 row affected (0.00 sec)

mysql> alter table gis_8 add spatial index(a);
ERROR 2013: Lost connection to MySQL server during query

The proper solution is to add NULLs support for spatial indexes.
We'll add this feature in the near future.

insert into gis_8 values ();

he could not create index again:

mysql>  create table gis_8 (a geometry not null);
Query OK, 0 rows affected (0.06 sec)

mysql>  insert into gis_8 values (GeomFromText('Point(1 2)'));
Query OK, 1 row affected (0.00 sec)

mysql> insert into gis_8 values ();
Query OK, 1 row affected (0.00 sec)

mysql>  alter table gis_8 add spatial index(a);
