TYPO3 Core

In one of my installations, the install tool database analyzer shows the following query to execute:

ALTER TABLE tx_foo_bar CHANGE l18n_diffsourc e `zzz_deleted_l18n_diffsourc e` MEDIUMBLOB DEFAULT NULL

The existing field contains really a space, which is fine for some databases. (sure in is this case it is a mistake)

After executing the query, this query fails:

Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '`zzz_deleted_l18n_diffsourc e` MEDIUMBLOB DEFAULT NULL' at line 1

I guess the problem is, that the field name is not quoted.
