PT 8.52 - random FTP transfers fail - AddAttachment

Hi everyone,

We upgraded from 8.50 to 8.52 a few weeks ago.

Since this time, some users complain about file attachments : when they clic on "Attach" with their file, the page goes automaticaly back on the menu.

It happens for all kind of files but only for specific users (same files work with another users).

The trace doesn't give any usefull informations and we can't see any FILETRANSFER.log to debug :

I changed sensitive data to X.
