            Bug ID: 300135
          Severity: crash
           Version: 4.8.2
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: KDE Crash Handler reported a failure when the user
                    restarted the system
    Classification: Unclassified
                OS: Linux
          Reporter: sayeed.ka at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.2)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

1.  The user was trying to attach some files to an e-mail message that was
being sent using Kmail.

2. Since the Kmail attachment function could not find the files (these files
were existing files that were displayed by Dolphin), the system was restarted
in order to resolve the failure of Kmail to find existing files that needed to
be attached to the e-mail message.

- Unusual behavior I noticed:

1. The user was attempting to attach files (that did exist in a folder) to an
e-mail message. However, the system did not display these files in the
attachment dialog box even though it should have displayed them. The user tried
to resolve this problem by restarting the system. After the user clicked on the
restart button the system shut down application windows and then dispayed the
KDE Crash Handler dialog box. 

2.  Also, the computer system was unusually slow.

-- Backtrace:
