TypeError: train() takes at least 5 non-keyword arguments (4 given)

How to Reproduce

While doing a POST operation on /admin/spamfilter/bayes, Trac issued an internal error.

Manually pasting spam into the text field and clicking train as spam/ham. The Mark selected as spam/ham options on the monitoring page also fail to train bayes, but in that instance it fails quietly. Both the stable SpamBayes 1.0.4 and development 1.1a6 fail in the same way.
