[Mailman-Developers] mailman-bundler-3.0b2: WSGI server error with zope.interface

[Tim Marx]

Hello,

I wanted to test the new mailman-bundler-3.0b2 and ran into a problem I 
could not solve.
I'm not sure if it's a problem with the mailman-bundler or with my 
machine. So I'm sorry for bothering you if the problem might be only on 
my server.

I installed the latest revision (#13) of the branch 
lp:~abompard/mailman-bundler/mailman-bundler in a fresh virtualenv with 
flag --no-site-packages (because of earlier install attempts that 
failed) located under /var/tmp/mailman.
I've created a user and a group ('mailman') who own the directory 
/var/tmp/mailman and I've added the user 'www-data' to the group 
'mailman' so there might be no permission problem in my opinion.
I followed the steps in START.rst (as 'production' installation) and 
everything worked fine so far.
Then I wanted to setup the Postorius/Hyperkitty frontend access with 
Apache and mod_wsgi (3.3). I used the supplied ~/deployment/apache.conf 
as basis and added VirtualHost directives and custom logging and so on 
but I didn't change the WSGI... directives.
Now when I try to access the configured domain I see always a "Server 
Error (500)" and the following stacktrace in my error log:
-------------------------------------------------------------------------------------

ImportError: cannot import name named
---------------------------------------------------------------------------------------
I have already found out, that this error occurs in zope.interface < 
4.1.0, but I've definitly installed version 4.1.1.
One interesting fact is, when I start the Django development server 
(with activated virtualenv) with './bin/mailman-web-django-admin 
runserver' this error doesn't occur.

Thank you very much for any ideas and help!
