Bug#859697: phpmyadmin: Can't install nor update to 4:4.6.6-2 due to dbconfig errors

[Piotr Górski]

Package: phpmyadmin
Version: 4:4.6.6-2
Severity: important
Tags: d-i

Dear Maintainer,

Package can't be installed due to dbconfig errors. Dbconfig makes bad entries 
in /etc/phpmyadmin/config-db.php:

<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded.  *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='10 phpmyadmin/db/app-user doesn' . "'" . 't exist';
$dbpass='';
$basepath='';
$dbname='phpmyadmin';
$dbserver='';
$dbport='3306';
$dbtype='mysql';
