When setting more than one block's title to '' (blank) Drupal dies, and
doesn't catch the SQL query error nicely. The error is as follows:
user error: Duplicate entry '' for key 2
query: UPDATE boxes SET title = '', body = ' ...<cut>... in
/var/www/html/drupal-cvs/includes/database.mysql.inc on line 66.

Using 4.6 build from 4/4/2005
The page ends with:
warning: Cannot modify header information - headers already sent by

There should be a check before the insert is attempted and if the block
title already exists the user should be notified with form_error().

this certainly doesn't solve the problem, but I've worked around this
issue by using html tags in the title field for blocks that I don't
want to show a title.

A small patch that checks to ensure the title does not already exit in
the Blocks list.  Also, if the field was left blank, in adds an HTML
comment with the current date to the second to ensure that a duplicate
title isn't created.
This is my first patch, so I probably did something wrong, but I'm
willing to fix it too.

I'm, personally, fine with how you've fixed the blank block title.
You've really solved two problems in one: duplicate titles (which is
the cause of this Issue), and the desire to have blank (or no) titles
(which is the reason for this Issue) for the end user. With that said,
I'm not a fan of your error message (but, then again, anal wording is
my specialty, so don't think I'm picking on you):
I'd rename it to "That block title is already in use; please choose
The goals here:

The user may not remember all the previous titles he's used.
Using "unique" starts forcing him to remember. We shouldn't do that.
The user already knows he entered it - we don't have to repeat that to
It's active, not passive (no use of "have").
Use a semi-colon, not a comma.
It's much shorter and concise.
