HTML, JSON attachments not showing

[kford]

Attached an HTML file and a JSON file to an email message in Roundcube. Sent myself the message. In message list view, email appears with a little "attachment" icon, but when viewing the actual message, you cannot download or otherwise access the attached files. If you view the message source, the attachments are present and base64 encoded. Attachments can be accessed when viewing mail via Horde.

Tried sending a single email from Roundcube with just the HTML file. Same result.
Tried sending a single email from Roundcube with just the JSON file. Same result.

If, however, I attach the same files to an email in Horde and send the email to myself, the attachments (from the Horde-sent email) are accessible via Roundcube.

The tested files were created with the "export html" and "backup" options available in FF when organizing one's bookmarks.

Used FF 3.5.9.
Running PHP 5.2.12.
