Package: nagios-mysql
Version: 2:1.3-cvs.20050402-1
Severity: important
Justification: strong suspicion a possible security update in sarge will
  exhibit the same issue

Basicly this is the same as:

#284902: Upgrade launces duplicate nagios

Except that now it fails to actually launch the second instance.

Apparantly, the above bug was not correctly solved, or re-introduced.
