[apport] senddigests crashed with IOError in __write()

[Thomas Bleher]

Binary package hint: mailman

To be honest: I didn't notice this flaw until apport signalled it; I once installed mailman, but completely forgot about it. I updated to Feisty a few days ago, and was running Edgy before (including all updates). I found mails in /var/spool/mail/list dating back to Feb 3.

The first mail is:
From: Cron Daemon <email address hidden>
Subject: Cron <list@thorium2> [ -x /usr/lib/mailman/cron/disabled ] && /usr/lib/mailman/cron/disabled
To: <email address hidden>

Traceback (most recent call last):
  File "/usr/lib/mailman/cron/disabled", line 220, in <module>
    main()
  File "/usr/lib/mailman/cron/disabled", line 149, in main
    mlist = MailList.MailList(listname)
  File "/var/lib/mailman/Mailman/MailList.py", line 128, in __init__

    self.__write()
  File "/var/lib/mailman/Mailman/LockFile.py", line 422, in __write
    fp = open(self.__tmpfname, 'w')
IOError: [Errno 2] No such file or directory: '/var/lib/mailman/locks/mailman.lock.thorium2.7148.0'

The second one is:
From: Cron Daemon <email address hidden>
Subject: Cron <list@thorium2> [ -x /usr/lib/mailman/cron/senddigests ] && /usr/lib/mailman/cron/senddigests
To: <email address hidden>

A little further digging revealed: I had deactivated mailman by
# cd /etc/rc2.d; mv S20mailman K20mailman
(which I believe is the proper procedure). This may have been causing this bug.

Thanks for your bug report.

Same here. The bug appears since I deactivated mailman.
Maybe there is a cron job trying to send digests without mailman being running...

[old_toby (simon-hornweb)]

I also get exactly the same crash (IOError in __write() ) with disabled and checkdbs.

I assume the status change was an accident?
