I just noticed the posting that you made to mailman-users.
I think that what is triggering the exception is the way you are
When you run arch the first time with the --wipe option, the existing
HTML archive content is deleted and the new HTML archive content is
generated by MHonArc from the list's .mbox content, assuming you have
set the list to use mhonarc as it archive page generator.
When you then run arch a second time without the the --wipe option
you are telling MHonArc to generate HTML archive content from the
same .mbox with the same content as on the previous run with the --
wipe option. But MHonArc does not find any new messages to add to the
HTML archive as it is being handed the same messages again. Normally,
MHonArc "optimises out" "duplicate" messages (based on Message-id: I
believe). I think that when it finds nothing to add to the HTML
archive it closes the pipe connection back to the Mailman process
prematurely, leading to the exception.
I will publish a revised MHonArc/Mailman integration patch to handle
this condition but in the meantime you should be able avoid the
problem by not running arch with the same input .mbox as on a
previous run. No loss, as the second run of arch serves no useful

I am trying to convert a list from the Pipermail archiver
I can run /bin/arch --wipe listname successfully.
I get this error when generating the MhonArc archive with
Pickling archive state into
Traceback (most recent call last):
File "./arch", line 202, in ?
File "./arch", line 190, in main
archiver.processUnixMailbox(fp, start, end)

self.mhonarcProcessUnixMailbox(input, start, end)
line 706, in mhonarcProcessUnixMailbox
status = mhonarch_process.close()
IOError: [Errno 32] Broken pipe
If I switch back to Pipermail it will run successfully.
It looks too that I miss March and April 2007 archives
when trying to convert to MHonArc, but Pipermail generates
them. Would this point to an problem in the .mbox file?
