Moodle 2.5 Upgrade - Broken!

Hi Everyone,

I am trying to upgrade a Moodle 2.3 site to Moodle 2.5 and I get the following error.

This comes up when I move the site from 2.3 > 2.5 or 2.3 > 2.4 >2.5 - always on the upgrade up to Moodle 2.5...

I have put a tracker ticket in as well https://tracker.moodle.org/browse/MDL-40370

Any ideas?

THanks

John
