Bug#603582: Priority extra breaks bugzilla's policy compliance

[Raphael Bossek]

Package: libdatetime-timezone-perl
Version: 1:1.20-1+2010k

Please change the priority of libdatetime-timezone-perl to "optional"
so bugzilla3 package can be "optional" too. bugzilla3 depends on
libdatetime-timezone-perl.

According to Policy Section 2.5: Priorities packages MUST NOT depend
on packages with lower priority values (excluding build-time
dependencies) nor should packages of priority optional (or higher)
conflict with each other. In order to ensure this, the priorities of
one or more packages must be adjusted.

Greetings,
Raphael
