This error is due to one of several known incompatibilities between

I read the FAQ, which was however last updated in 2009.

This MIGHT not be a problem, because I'm running tests (as a sort of power
user) on my machine (suse 11.3 installed last december), but this is NOT
the target system. I'm pretty sure the target system will have suse 11.4
which came out recently.

suse 11.3 bundles mailman 2.1.11-13.2 and python 2.6.5-2.11 (however they
provide separately mailman 2.1.14-21.1 and python 2.7-43.1)

suse 11.4 bundles mailman 2.1.14-4.7.1 and python 2.7-8.2 (and provides
also 2.7-43.1)

I am really confused by all these minor subsubversions.

Is the suse 11.4 mm/python coupling sound ?
If so I will tell our sysadm to proceed, and pass on my test experience.
I might do a few further tests on my machine and occasionally report
problems here (be free to reply "usual 2.1.11/2.6 incompatibility").

Eventually I could upgrade mailman on my test machine (but not python)
if that is likely to work (just to test also the upgrade procedure).
If suse is packaging Mailman 2.1.11 with the Python 2.6.5 that you are
apparently using, this is a serious suse packaging problem.
I could report a bug, however if their 11.4 packaging is sound, they are
likely to consider it irrelevant.

    Yes, but the key part in this case is

    "Update - March 2009: Mailman 2.1.12 has been released and requires
    Python 2.4.x or later. It is the *first* Mailman release compatible
    with Python 2.6." (emphasis mine).

    Everything to the right of the hyphen (-) is a designation by the
    packager of build, patch level, whatever. Only suse can tell you what
    it means.

    I strongly suggest that for a fair test, you upgrade the Mailman on
    your test platform to the 2.1.14 package. The suse 11.3 bundle has the
    compatibility issues you have already seen and others as well.

    Is the suse 11.4 mm/python coupling sound ?

    It should be, but I don't think the combination of Mailman 2.1.14 and
    Python 2.7.x has seen much use, so there may be as yet undiscovered
    issues.

    If so I will tell our sysadm to proceed, and pass on my test experience.
    I might do a few further tests on my machine and occasionally report

    Eventually I could upgrade mailman on my test machine (but not python)
    if that is likely to work (just to test also the upgrade procedure).

    I would recommend that.

    If suse is packaging Mailman 2.1.11 with the Python 2.6.5 that you are
    apparently using, this is a serious suse packaging problem.
    I could report a bug, however if their 11.4 packaging is sound, they are
    likely to consider it irrelevant.

    I suggest you report it anyway, if for no other reason than to document
    the issue with suse.
