[imp] Reply and Forward windows broken with certain mail messages

[Ruben Squartini]

Hi Michael!

After setting up the latest "-git" version of Horde 5 (5.1.0-git +
6.1.0-git) (pulled few minutes ago), problems related to preview are fixed,
but the same mails are not visible in either Forward or Reply windows.
Either in HTML or Text only composition.

Could you check if you can do the same kind of wrong charset detection in
those?

In the 6.0.4, going from HTML to text showed the contents of the message in
the composition window, now that is not the case anymore.

Both the customer and us are pushing this migration, then any
information/feedback/testing you need is first in our task list.

Regards,
Ruben.
