= Description =

When using features that send out emails (page change notification, send login data) I get an error page with "ImportError: No module named Header". 

== Example ==

 1. Go to http://eyfa.benn.org/wiki/
 1. Click User Preferences at the top right
 1. Enter "user@host.com" as your email address and click "Mail me my account data"
 1. You get an error page

== Details ==

See error page at the example.

I use a standard installation of Python on SuSE 8.2. I added some Python related packages via Yast but otherwise I didn't change anything.

Here is some output from the error page:

This might be a fault with my Python installation or version. Any ideas?

This is not a bug. You need python >= 2.2.2. I will include some workaround in moin 1.2.2.

= Discussion =

Quick workaround: edit /usr/lib/python2.2/site-packages/MoinMoin/util/mail.py - comment out the line
    from email.Header import Header

and replace the line 

    msg['Subject'] = Header(subject, config.charset)

with

    msg['Subject'] = subject

IMHO, installer should check python version and complain if it's incompatible.

Comment: The workaround works great, thanks!

## This part is for Moin``Moin developers:

 * Priority: 
 * Assigned to: ThomasWaldmann
 * Will be worked around in release: 1.2.2
