mod_rewrite to a specific controller

[eluser]Phil Sturgeon[/eluser]
What am I missing here?

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine on

RewriteBase /

RewriteCond %{REQUEST_URI} ^/([a-zA-Z0-9_-])$
RewriteRule ^(.*)$ index.php/profiles/redirect/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

I bolded the part with the issue. The idea is that example.com/profilename goes to the controller, while example.com/something.html or example.com/something/somethingelse.html all go through to index.php. The problem is, my first rule is ignored.

Any ideas? It's late, I have been coding for almost 20 hours and I want to go to sleep...
