I did eventually manage to reproduce it; the problem has no effect on
the build (the traceback is essentially cosmetic), but it seems this
is in fact a bug in python-nevow.

python-nevow installs a twisted plugin and thus has code in the
postinst to regenerate the plugin cache; however, this code runs
before pycentral pkginstall is invoked to actually make the plugin
available, thus on a fresh install of python-nevow, the plugin cache
will be out of date once installation is complete.
