Error upon "Save and Continue Editing"

[whalesalad]

I was writing a blog post and then clicked "Save and continue editing" to preview it before it went live, only to get the following error.

WordPress database error: [Query was empty]

Warning: Cannot modify header information - headers already sent by (output started at /home/mwhalen/sites/whalesalad.com/wp-includes/wp-db.php:160) in /home/mwhalen/sites/whalesalad.com/wp-includes/pluggable.php on line 388

Should have done an svn update first. This is no longer a problem of mine. I just did an update (10:33pm on Sat, Oct 20th).

I'll leave the ticket here for you guys to check out though.

That issue was resolved as #5145. It was to do with the Database prepare() functionality and having % marks in a post.
