Investigate Freeside account registration

For some reason, the Freeside account creation system is throwing a HTTP 500 Internal server error when verifying a new account. A link such as this one:

https://profiles.freeside.co.uk/verify/cb6d539d-de25-4631-8341-2622088e6165

Is clicked, 2 pages of forms are clicked through, and then it throws the 500.

We should investigate why this is happening - starting with analysing the server logs.

Looks like an authentication exception - certainly unexpected.
