when i click to the reply button for a certain mail from a friend of mine, the
composer opens with two "To" lines. 
To Käser
To Christian <christian.kaeser@censored.de>

they use an exchange server so send their mail. looks like it is possible
to configure a "strange" from: in a e-mail (exchange !). here is the relevant mail source:

The problem seems to be the iso-8859 charset definition the the "From:" line,
which is not handled correctly. i do not know if that is standard compliant or
not (if there is a standard at all) but it would be nice if kmail would support
that, otherwise i have to fix the two Tos myself everytime i reply a mail. 

i have exactely the same problem with an old mozilla mail client (jfyi)

should be easy to reproduce.

thanks in advance,
Andy
