Any references to this happening on Linux? I'm not interested in what
happens on Windows, it's a completely different situation. The
filesystem API is different (and broken IMHO), the desktop is totally
different in architecture etc. etc. Apples and oranges.

Neither am I, as I said, but I don't think it matters.

Irrelevant. You can't compare a browser and an email client. Note that I
don't claim that no file can be corrupted by a crash, even on a
journalled filesystem. I do claim that a properly written mail client
should be able to deal with it without losing mail. If you feel safer by
carefully quitting your mail client before logging out or shutting down
by all means go ahead. I think it's not worth the effort.

The browser offering to restore state or start with a clean slate is a
user convenience, especially if it crashed because of a specific web
page. In fact some browsers ask you the same question even if do quit
them cleanly. This doesn't affect the argument about mail clients in the
slightest.

This is purely anecdotal. You're describing what you do without
justifying why you do it. I use Evolution for most of my mail and it
does have bugs which occasionally mean you have to kill it, but it's
never lost a message. In the worst case it might have failed to update
some IMAP server state and some messages which I've already marked as
read appear as new, or if I was in the midst of composing a message it
might ask if I want to restore it, just as many editors do. I don't have
much recent experience with TBird but I'd be surprised if it were
substantially different.
