Problem reading some mails

[tn fenster <balsa ars-solvendi de>]

Hello,

I have problems reading some mails with balsa-2.2.0 as no content at  
all can be seen in balsa. It seems to me like the problem is caused by  
the following lines:

Content-Type: multipart/alternative; boundary="=_alternative
       004FBE5AC1256ECF_="

as there should be no newline after _alternative. Changing this to

... boundary="=_alternative 004FBE5AC1256ECF_="

directly in my inbox-file makes the eMails show up correctly. Is this a  
problem / bug with the sender's eMail-client or could balsa handle this  
better? And if it's a bug on the other side, is there a way for me to  
read those messages without viewing the source or deleting that  
newline?
