the 1.27.4 patch does not seem to be working as expected.

You get the following error when attempting to apply the 1.27.4 patch:

I've managed to force this by updating the parser/Parser.php file to call text() instead of getText() at link 3694, the sql issue was resolved by adding engine=myisam to the end of the table create command.
