Random thought: caused by the link clicked? Try this one for me? Weak
possibility, but I thought no use in "ass-u-me"ing.

Heh. As mentioned in my other post, hadn't had 2nd cup yet. It is indeed

Ditto: T'bird version (20081120)

Yep. I did go to another account, but it uses evolution. The problem
didn't manifest itself using evolution. I'll go to another that uses
T'bird and try there. Then, a fresh account.

The fact that I can reproduce it on that account leaves me sure that
some kind of bug exists. It may only be exposed by some odd-ball thing
in that account or directory structure, like permissions or whatnot.

I'll investigate more throughout the day, as workload permits.
