Following 1.9.2.3 update order view from admin page not working?

Question

Is there a fix this or is it expected that a further imminent update will fix. Is it possible to find information on when a fix may be due?

Site not fully usable with this error in place and although I have a backup prior to update I now have fresh orders stacking up which I will need to re-enter manually I presume if I go back to my backup. Any advice appreciated.

This problem is only affecting Magento websites running on PHP < 5.4
