Just tried to reproduce this behaviour - successfully! Opening an unread mail (of course including attached files) works properly, reopen the same mail with status "read" works, too. After switching to any other desktop (on XFCE) and back then, the same mail causes the bug described above! Marking the mail "unread" makes Thunderbird display the list correctly again.
