The only htaccess with rampage is located in my Horde root, I have a
PEAR install, though:

# IMPORTANT: DO NOT EDIT THIS FILE!
# It will be overwritten with any future upgrade.

allow from all

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
    RewriteCond   %{REQUEST_FILENAME}  !-d
    RewriteCond   %{REQUEST_FILENAME}  !-f
    RewriteRule ^(.*)$ rampage.php [QSA,L]
</IfModule>

Do you have simimliar htaccess files in other app's root directory? What
happens, if you disable [rename] the file?
