tasksel remove mail-server removes LAMP and postgresql

[Robin Stein]

Binary package hint: tasksel

#tasksel remove mail-server removes these packages:
apache2 apache2-mpm-prefork apache2-utils apache2.2-common dovecot-common
  dovecot-imapd dovecot-pop3d libapache2-mod-php5 libaprutil1
  libdbd-mysql-perl libgpgme11 liblockfile1 libmysqlclient15off libpq5
  libpth20 mailx mutt mysql-client-5.0 mysql-common mysql-server
  mysql-server-5.0 openssl php5-mysql postfix postgresql postgresql-8.2
  postgresql-client postgresql-client-8.2 postgresql-common postgresql-contrib
  postgresql-contrib-8.2 procmail ssl-cert

I get this error when removing packages:
Use of uninitialized value in concatenation (.) or string at /usr/bin/tasksel line 349.

Very similar bugs, but not setting them as duplicates yet: I'm not sure whether they are real duplicates, as they have different tasksel versions and/or mention different tasks:
bug 250287
bug 150282
bug 131202

In my previous comment I made a typo: 150282 is an entirely different bug. That should have been bug 150252. It is currently triaged and has importance high.

I will mark this bug as a duplicate of bug 150252. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug can best occur in the other report. Feel free to continue to report any other bugs you may find.
