Neither of the email scripts from contrib in 2.21.1 submit attachments to the bugs...
New tickets can be created with bug_email and new comments can be added with the append script but attachments never make it to the bug. They do however linger in mimedump-tmp
I'm surprised bug_email worked at *all* in 2.22, since it was completely broken as far as I know.
