Mozilla’s Thunderbird was updated to version 2.0.0.9 two days ago and I realized that my (self-installed) TB was still 2.0.0.6. So I started my mail client with root permissions, cause the “update thunderbird” was grey as standard user (still don’t know how to fix it, I’ve installed it manually for trying the new TB2 features).
The first problem: I got a virgin application… All my mails… GONE!!!! I don’t know why, but I got a more or less empty prefs.js, but after replacing it was an (older) security copy, everything was fine again.
And today? I found a bug that I did not notice as a bug yet. I searched for an email, I sent to myself some hours ago (from work) and I didnt find it in the inbox. But I had some duplicate entries (3 mails were shown twice). One of the new TB2 features revealed the miracle: One of these “duplicates” was my “missing” mail. I found it in a virtual folder which shows the newest mails of all of my (imap) inboxes (The are lots of possibilities to configure those kind of folders). And how to fix it? I did not find a solution yet, but a workaround: I just moved one mail to another folder, opened this folder an moved the file back: yeah, splitted again… both mails are back.
