This error is due to one of several known incompatibilities between

FAQ at <http://wiki.list.org/x/pYA9>.
I read the FAQ, which was however last updated in 2009.

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).

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.

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
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).

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.
