Modrewrite Problem auf der Startseite

Hallo,

an was kann dies liegen:

Wenn http://www.domain.de/kategorie aufrufe, -> https://www.domain.de/kategorie/ = KORREKT

wenn ich http://www.domain.de aufrufe, -> https://www.domain.de/%/ = macht er mir die Komische 25 dran

Code:

<IfModule mod_rewrite.c>
    Options +FollowSymLinks
    RewriteEngine On
    RewriteBase /

    RewriteCond %{HTTPS} off
   # RewriteRule (.*) https://%{SERVER_NAME}/%$1 [R,L]

    RewriteCond %{HTTP_HOST} ^www.domain.de [NC]
    RewriteCond %{SERVER_PORT} 80 
    RewriteRule ^(.*)$ https://www.domain.de/$1 [L,R=301] 

    RewriteCond %{REQUEST_URI}     config\.inc\.php [NC]
    RewriteRule ^config\.inc\.php  index\.php       [R=301,L]

    RewriteCond %{QUERY_STRING}     fnc=(getShopVersion|getShopEdition|getRevision) [NC]
    RewriteRule ^(.*)$              $1?                                             [R=301,L]

    RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
    RewriteRule .* - [F]

    RewriteCond %{REQUEST_URI} oxseo\.php$
    RewriteCond %{QUERY_STRING} mod_rewrite_module_is=off
    RewriteRule oxseo\.php$ oxseo.php?mod_rewrite_module_is=on [L]

    RewriteCond %{REQUEST_URI} !(\/admin\/|\/core\/|\/application\/|\/export\/|\/modules\/|\/out\/|\/setup\/|\/tmp\/|\/views\/)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule !(\.html|\/|\.jpg|\.css|\.pdf|\.doc|\.gif|\.png|\.js|\.htc|\.svg)$ %{REQUEST_URI}/ [R=301,L]

    RewriteCond %{REQUEST_URI} !(\/admin\/|\/core\/|\/application\/|\/export\/|\/modules\/|\/out\/|\/setup\/|\/tmp\/|\/views\/)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule (\.html|\/)$ oxseo.php


    RewriteCond %{REQUEST_URI} (\/out\/pictures\/generated\/)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule (\.jpe?g|\.gif|\.png|\.svg)$ getimg.php
