Was this a new list or one that was present during a prior successful
cron/senddigests run?

Could you access the list via the web UI?

What user runs the cron, i.e. the owner of the crontab or the listed
user is a system crontab, and can that user access the config.pck file?
Can that user successfully run cron/senddigests manually?

If the above doesn't give clues, maybe apparmor is involved.

Maybe it was a transient glitch.

In any case, I wouldn't expect re-installing Mailman to correct a
permissions problem if check_perms didn't find anything.
