I thought I'd fixed the unicode bugs, sorry - will try to investigate when
I have a moment to spare.  The original intention was that old jobs would
be restorable in newer releases but there are practical limitations to this
due to the complexity of the information that's being stored.  I suspect
the error message is the explanation for what's breaking, but there are
other problems too, such as the structure and types of the configuration
parameters changing in a way that breaks the lower-level code, and it has
been difficult to catch these in advance.

Another thing I noticed about some of these jobs was that there are

Yes, these should definitely be deleted.
