The general idea about pointing at extensions here is that such bug in
Mercurial should be caught by the Mercurial test suite (or local
development process) so user should not be exposed to it (in theory). On
the other hand, existing extensions code might use API wrong in a way
that did not raised the error in previous version. So if the user get
exposed to that error, it it probably because of an extension.
