We use drupal for one of our websites. When clean URL module is activated, drupal adds the following lines to the .htaccess file
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
URL in the form http://example.com/user is supposed to be re-written by http://example.com/index.php?q=user
Instead, it is rewritten by http://example.com/index.php and the query string is somehow lost despite the QSA option.
This is how the rewrite log looks like

It looks like the rule parsing goes fine, but then, the query string is stripped. Why is that?
That is, if you called your code with /user?foo=bar and DID NOT use QSA, then ?"foo=bar" would be replaced by "q=user". If you DID use [QSA], then "q=user" would be appended to "?foo=bar" giving the query string "?foo=bar&q=user".
So, I doubt that [QSA] has anything to do with this. You code looks OK, though. Therefore, I would suggest trying to put some "echo" statements into your Drupal code, to see where and how the query string is being dropped.
As a last-ditch method, you could temporarily change the mod_rewrite code to do an external redirect, and then use a server headers tool to see if you're getting recursion or some other problem that results in the query string being dropped. I like the "Live HTTP Headers" add-on for Firefox/Mozilla browsers, but there are others, as well as some on-line server headers checkers. Be sure that whatever tool you use, it shows *all* headers and transactions, though -- some don't.
Be aware that in RewriteLog, query strings are "rarely mentioned." That is, just because the log says you're internally redirecting to a URL-path with no query string appended to it, that does not mean that there is no query string appended to that URL-path. Compare to a RewriteLog entry for a successful query-string rewrite if this is not clear.
