ThunderBird, the open source e-mail application, contains a mail handling issue (BugZilla, please change your referrers) which is causing some e-mails to fail to display. The e-mails have been received, but as they are invisible they may as well not have been. In addition, the recommended practice of compacting folders will cause the invisible e-mails to actually be deleted permanently. The issue, which was discovered well over 2 weeks ago, has been patched for the 1.8.0 branch of ThunderBird — but there has been no word of an official new release or patch before the regularly scheduled December release of version 1.5.0.9.
