mod rewrite redirect issue
===

i have this .htaccess file:
    Options +FollowSymlinks
    RewriteEngine On

    RewriteRule ^([a-zA-Z0-9_-]+)$ profil.php?user=$1 [NC]
    RewriteRule ^([a-zA-Z0-9_-]+)/$ profil.php?user=$1 [NC]
    RewriteRule ^([a-zA-Z0-9_-]+)/galerie$ galerie.php?user=$1 [NC]
    RewriteRule ^([a-zA-Z0-9_-]+)/galerie/$ galerie.php?user=$1 [NC]
    RewriteRule ^(.*)/galerie-(.*)_(.*)$ galerie_poze.php?user=$1&album=$2&page=$3 [NC]
    RewriteRule ^(.*)/galerie-(.*)_(.*)/$ galerie_poze.php?user=$1&album=$2&page=$3 [NC]
    RewriteRule ^(.*).php?$ index.php?request=$1 [QSA,L]

and it doesnt seem to work...
here is my problem: when i want to access a page on my site for example site.com/test.php
it redirects to index.php?request=test
the problem is that i also have "profil.php" and "galerie.php" that i dont want to pass trough index.php instead when i do this: site.com/username/profil i want it to point to profil.php?user=username, but it doesnt work....

what am i doing wrong?
