Pigeonhole Sieve fails on date-based filter rules - bug?

10 Feb 2016

      Hi list!
I’m running dovecot + pigeonhole on a debian wheezy based VPS.
Here is the output of „dovecot -n“
# 2.2.18: /usr/local/etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.8 (0c4ae064f307+)
# OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9

I’m trying to filter emails based on the following rule:
if allof (date :value "lt" "Date" "date" "2015-01-01")
{
fileinto "Archiv/2014";
}
Some mails which should match are not filtered.
Please look at what
sieve-filter -e -W -v ...
puts out:

So it appears that the „Date“ header is not properly extracted for the affected emails.
Here are the headers of an particular email (the one without „Date:“ listed above):
