problem with acknowledge ID

Hi,

With the snapshot of 20070207, some alert e-mails come with "0" as ID.

Edxample: Subject: Hobbit [0] eliot:sslcert warning (YELLOW)

The corresponding entry in acknowledge.log is:

1170845489 0 1440 0 np_filename_not_used eliot.sslcert yellow bb at iris.unil.ch wrote:\nAcked by: Dominique Frise Dominique.Frise at unil.ch

How can we trace/debug this?
