It would make more sense to rename https://jira.toolserver.org/browse/PYWP from pywikipedia to pywikibot
and fill new rewrite/ bugs overthere, if others agree on that.
This is probably the best suggestion. JIRA rocks - except for the import of bugs. If we use it for the rewrite branch, there is no need for importing any bugs - so we do have the benefits, but not the disadvantage :-)
Oh, and seriously, bugzilla is even worse than the sf.net tracker. At least the sf.net tracker has a sort-of-sensible interface.
