Bug#301587: apt: Odd recommendation on dist-upgrade (upgrade gets it right)

[Jefferson Cowart <jeff@cowart.net>]

Package: apt
Version: 0.5.28.1
Severity: normal


This afternoon when I ran a dist-upgrade on my sarge box I got an odd
recommendation about upgrading php4:

# apt-get dist-upgrade -u
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Done
The following NEW packages will be installed:
  apache-common libapache-mod-php4
The following packages will be upgraded:
  libapache2-mod-php4 php4 php4-common php4-mysql
4 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 0B/4314kB of archives.
After unpacking 6264kB of additional disk space will be used.
Do you want to continue? [Y/n] n

# apt-get upgrade -u

php4 declares a dependancy on libapache2-mod-php4 or libapache-mod-php4.
Thus I don't understand why it wants to install apache and
libapache-mod-php4 when the apache2 version of both of those packages
are already installed.
