I've discovered what happened; it was really quite simple.
I implemented a method:
Then I deleted MCNamespacedStWriter for some reason; then I decided that
it was worth keeping after all and added it again. Obviously what
happened was that MCNamespacedStWriter was obsoleted making the literal
association in the compiled method refer to the obsoleted class.
When you remove a class, is there an easy way to find all "references"
to that class in a similar way to how all senders of a method can be
found? If so, then I consider the above to be a bug; the browser should
have alerted me to the fact that there were references to that class
from some methods.
