Could it be that your hoster activated some security mods in Apache?

try this in .htaccess ( I found it for uploading images to Wordpress, situation is the same):

Code:

# <IfModule mod_security.c>  
<Files async-upload.php>  
SecFilterEngine Off  
SecFilterScanPOST Off  
</Files>  
</IfModule>

but generally HTTP: Errors 500 are not client-side, so you must contact your hoster
