Hi Peter,
I had to admit to being quite confused right now. I've been totally
failing to reproduce the issue now.
I rolled back the commit in my code, where I changed from txn_do() to
using txn_scope_guard(), and I'm still not seeing the problem. (Which
was that DBIx::Class was stringifying the object and prefixing it with
"DBIx::Class::txn_do error:" or similar.)

I specifically made that change to solve the problem I mentioned above
-- so I'm really confused as to why it has now disappeared. I haven't
upgraded any CPAN modules since then.

W.T.F.
