           Summary: Email header fields saved empty when contains unicode
                    characters and punctuation (dash, dot)
           Product: kmail2
           Version: Git (master)
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: composer
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: MurzNN at gmail.com


Version:           Git (master) (using KDE 4.6.2) 
OS:                Linux

Tested on kdepim from GIT 2011-04-17, and can reproduce on earlier versions
(beta4) from 2011-01-15.

If I fill from, to, cc, bcc fields with text: 
Интернет компания example <example at example.com>
it saves and sends normally.

But if I add dash to the name:
Интернет-компания example <example at example.com>
it saves and sends with this field empty!
This field is absent in message source:


I test English equivalents:
Internet-company example <example at example.com>
Internet-company my-very-very-long-name-of-company.com <example at example.com>
and its works normally, so the problem, I think, is near utf-8 decoding.

Here is screenshots:

Saved message: http://wstaw.org/m/2011/04/18/plasma-desktopQf2613.jpg

Reproducible: Always

Steps to Reproduce:
1. Create new message, fill "Интернет-компания example <example at example.com>"
to the "To" field.
2. Save as draft.
3. Look at the field "to" in saved message from drafts folder

Actual Results:  
"To" field is empty, and it absent in message source!

Expected Results:  
"To" field must contain "Интернет-компания example <example at example.com>"
