            Bug ID: 318915
           Summary: Surplus angled bracket freezes sending operation
    Classification: Unclassified
           Product: kmail2
           Version: 4.9.5
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: composer
          Assignee: kdepim-bugs at kde.org
          Reporter: hara1br at gmail.com

KMail version: 4.8.5, openSuSE 12.2
I composed an email with several recipients. One recipient address which I
copied from another email had a surplus angled bracket ">" at the end of the
string (my error, didn't catch it). When I pressed "Send", I saw a message 
[quote]email at domain.com>
The email address you entered is not valid because it contains too many closing
angle brackets.[/quote]
I cklicked OK and then the whole composer window with this email WAS GREYED OUT
and did not react to user actions. 
There was no way to edit anything in this window, to close it or do anything
with it.  
Apparently the error processing after the address check has a glitch because it
does not gracefully offer either 
(a) that the user corrects the recipient address and tries again to send the
email, or, less desirable
(b) that the user can at least in a final action close the window where the
error occurred.

When I closed the KMail main window, a message appeared which offered that I
save the pending email to the Drafts folder which I did. I restarted KMail,
opened the email in the drafts folder and the offending recipient address had
been corrected!


Reproducible: Always

Steps to Reproduce:
1. Compose a message with a wrong recipient address (example: surplus trailing
angle bracket)
2. Try to send it
3. Click on OK when KMail reports the error 
4. Bingo, the "dead" window is there.
Actual Results:  
Close the KMail program.
Accept to save the pending email to the drafts folder.
KMail AND THE GREYED-OUT window both close.
Restart KMail, open the saved email. It shows a corrected recipient address and
could now be sent if you want.

Expected Results:  
Of course, no "dead" window. 
Let the user manually correct the offending email address or, since KMail
obviously attempts to correct the address itself, present the user with this
corrected result and let him try a second time to send this email.
