I did an "apt-get -u dist-upgrade" just earlier. Mozilla-thunderbird, among other things, was upgraded. I then reboot, having just upgraded my kernel. After the reboot I soon launch up mozilla-thunderbird only to discover that all my mail's gone. I had some very important mail in there.
I always used just the default profile so that's not it.
Has this happened to someone? Where does mozilla-thunderbird keep my mail and how? Does anyone have an idea of what I can do? Please?
