If I delete the .htaccess file (renamed it), phpmyadmin comes up as 
expected!

So what's wrong with .htaccess:

DirectoryIndex index.php
Options +FollowSymLinks
Order allow,deny
Allow from all
<IfModule mod_mime.c>
<IfModule mod_php4.c>
AddType application/x-httpd-php .php
php_flag magic_quotes_gpc Off
php_flag track_vars On
php_flag register_globals Off
php_value include_path .
</IfModule>
<IfModule mod_php5.c>
AddType application/x-httpd-php .php
php_flag magic_quotes_gpc Off
php_flag track_vars On
php_flag register_globals Off
