The fake 0 sec. sessions make reading the list difficult.

Probably this is not a bug of last from SysVinit, but I can\'t find a better category for the bug report.
Comment 1 Dmitry V. Levin 2002-02-11 15:02:31 MSK 
No, last is innocent.

The bugs are in sshd/login pam configs.
They do lastlog manipulations and use pam_lastlog - it\'s mutially exclusive.

Default login and sshd configs are affected.

Relocating bug report to login package.
