Do you have sufficient access to the server to be able to see 
mod_rewrite's log files (which can be enabled with 'RewriteLog' if 
necessary)?  If so, you can debug the process to see what your regexp is 
actually doing.
mod_rewrite rules involve a lot of trial and error in my limited experience.
You could try it without one of the ?s, since if it doesn't match, the 
rule shouldn't get invoked anyway:
RewriteRule ^([^/]+)/?$  user.php?username=$1    [L]
You don't need QSA if you're not expecting '?...' on the end of the URL 
before the substitution occurs.
Another untested thought: does the '.' in the username need to be 
escaped, i.e. converted to %2e  ?  Don't ask me how though...
Good luck
Chris
