attachment error in emails module

[manuele]

Hi, I'm using SugarCRM 5.2.0a (Build 5447) (upgrade from 5.1 installation), and when I try to send an attachment I have these errors:

Warning: mime_content_type(cache/modules/Emails/6aca8afd-e83a-9689-ea94-48916b3fb781/51b0d4ef-9174-dbab-9439-49afeda65498Cmyfile.pdf) [function.mime-content-type]: failed to open stream: No such file or directory in /var/www/modules/Emails/Email.php on line 325

while(1);/*{"composeLayoutId":"composeLayout7"}*/

Any suggestion?

I get the same error in a 5.0.0c. But the emails get sent even though the error occurs. Any ideas?
