[Users] HTML rendering problems

[Ralf Mardorf]

Under

Configuration > Preferences... > Message View > Text Options >
HTML messages >

I chose

[x] Render HTML message as text
[ ] Render HTML-only messages with plugin if possible

and

Select the HTML part of multipart/alternative messages

is just the default selection, so checked or unchecked, both have got
pitfalls. If unchecked some messages are "empty" by default, if checked
quotes and line wrapping of some messages is "fishy" by default. You
need to use the buttons on the right, if you check or uncheck this
option.
