Aaaah, of course! Hmm, I don't know how to catch that in general... it
was a yaml-cpp version mismatch since we upgraded the bundled version
between releases. It's also not unknown to have problems with the Python
modules from previous releases: a clear-out before reinstallation is a
good plan!

Cheers,
Andy
