How does one report a bug against a collective component?

Specifically, pas.plugins.sqlalchemy gives me this traceback:
2011-01-30 23:43:21 ERROR Zope.SiteErrorLog

TypeError: Boolean value of this clause is not defined

This should fix it (because 'clause' may be a
<sqlalchemy.sql.expression.BooleanClauseList object > or None):
