assuming by "last line" you mean the rewrite rule, I just commented it out and everything worked but obviously the url is not getting changed.
I've also tried changing my .htaccess to the one provided in the above mentioned wiki article and i don't get the error but I also am not getting any changes.
and yes I've restarted apache several times, even rebooted my system.
