            Bug ID: 357681
           Summary: KMail crashed when trying to drag-select list of
                    recent addresses in Settings dialog
           Product: kmail2
           Version: 4.14.1
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: znerol at gmail.com

Application: kmail (4.14.1)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.2 (jessie)

-- Information about the crash:
- What I was doing when the application crashed:

>From a composer window, selected Settings -> Configure KMail...

Clicked on Composer section. In there, clicked on Edit Recent Addresses.

Only a few entries were there. From an empty part of the list field, I tried to
drag-select the list of entries. No select box was shown, but before I could
even let off of the mouse button, the whole application crashed.


I re-tested without involving a composer window; just opened KMail settings
from the main window. Same thing - although it took a few extra drag-select
attemtps before it finally crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
