This is a strange error.

The traceback says Mailman's qrunner was trying to execute the command line 
you defined via the PUBLIC_EXTERNAL_ARCHIVER config variable with the 
listname concerned plugged in to it.

Mailman does this using the Python os.popen function which provides a 
writable pipe through which the qrunner feeds the text of the email 
concerned to (hopefully) Mhonarc's process STDIN.

It looks as though Mailman has checked the exit status of the command 
returned via the close function on the file type object returned by popen, 
and found it to be non-zero.

However, when trying to output this exit status to the logfile it has 
failed because the exit status was not an integer but a string. UNIX 
command exit status is supposed to be a 16 bit integer.

The question is why the exit status is a string not an integer. I cannot 
reproduce this despite feeding absolute nonsense commands of various types 
to os.popen using either the Python 2.2.1 or 1.5.2 I have readily available.

It looks, from information in the traceback, as though you are running MM 
2.0.x and not running Python 1.5.2 but a later version.

To get any further, some information about what OS and version and which 
versions of Mailman and Python you are using may be useful.

It may be that this is a Python bug rather than a Mailman specific problem.
