            Bug ID: 304016
          Severity: crash
           Version: 4.8.4
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: kontact crash : kmail2 if restored from last session
                    and wait for kwallet and cancel imap account
    Classification: Unclassified
                OS: Linux
          Reporter: brunofr at ioda.net
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4) "release 513"
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.16-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
How to reproduce : have several imap accounts, each of them store the password
in kwallet. 
Open kontact, in mail module. Close your session and shutdown your computer.
Restart (was on another network in my case) and open your kde session.
My setup is to restore any opened programs.
so kontact start and kwallet open its dialog box to unlock password.
I wait several minutes, and one of the account ask for its password.
I enter the kwallet password, and cancel the imap account.
Few seconds later I get this backtrace.

First even if there's a timeout for kwallet, I find strange that the imap
account was proposed. Then the crash if you cancel the password entry is wired
:-)

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
