[Evolution] Warning message about HTML

[Bart <montana_evolution_user hardinmt us>]

Evolution 3.8.3
openSuse 12.3
KDE 4.10.3

I create a message using HTML format.
I choose a recipient from my contact list, the On This Computer ->
Personal one.
I enter a subject
I click Send
I get a popup that asks if I really want to send this message in HTML
format although the recipient's information has the "Want's to receive
HTML mail" box is checked.

This does NOT happen on all contacts!  Just some.  I can't seem to
detect a pattern.

This is not a new problem, nor is it serious.  I was just, oh I guess
bored, and decided to ask about it.
