OK, I've tracked down one place where it's occurring and it's mea culpa.

In my custom override for RT::User::CanonicalizeEmailAddress I was
assuming that I was being called as an object method but in fact it's as
a class method.  So $_[0] is the string 'RT::User' rather than a valid
object.  I was using it to call other RT::User methods that expect a
valid object and this error was occurring when they were trying to test

I discovered this because the error occurred in a different place in my
development world and included a stack trace.  So I'm not 100% convinced
it's the same instance but the only way to see is to push a fix out to
production and see if it stops the error from occurring.
