This is a Pyramid bug.

transaction.note is defined to take a bytes string.  Pyramid
should encode the path before passing it to transaction.note.

Alternatively, Pyramid could store the path in transaction
extended info, which accepts any picklable type.

Of course, we could revisit this.  If we did, I'd deprecate the
transaction user and description attributes and only support
meta data via the extended info mechanism, which I'd rename
"meta data".
