            Bug ID: 310654
          Severity: crash
           Version: 4.9.3
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: KMail crash upon accessing KWallet
    Classification: Unclassified
                OS: Linux
          Reporter: leibaokai at sina.cn
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kmail2

Application: kmail (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

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

I've just added a new Smtp server in KMail and set it to remember the password.
Confirming the dialog, a KWallet dialog appeared, asking me if I want to allow
KMail to access KWallet. Upon clicking "Always allow", KMail crashed.

This is using the latest KMail 4.9.3 from the Kubuntu ppa on Kubuntu Quantal
Quetzal.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
