Errno 36: filename too long -- stops mail delivery

[Ariebs]

A user sent a Bugzilla page with an auto-generated
filename (basically, the query used to generate the
page) as an attachment.

Unfortunately, this filename is long enough to
overwhelm the pathname limit on Linux ext3 file
systems. (See below.) This, in turn, prevents
subsequent mail from being delivered.

Version info:
mailman-2.1.4-2.3.100mdk as distributed with
Mandrake Linux release 10.0 (Official) for i586

For example,

$ /usr/bin/python -S /usr/lib/mailman/cron/senddigests
Traceback (most recent call last):

Upgrading to MM 2.1.6 and setting the configuration variable
mm_cfg.SCRUBBER_DONT_USE_ATTACHMENT_FILENAME = True
might avoid this problem
