          Severity: crash
           Version: 4.8.2
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Kmail failed when I clicked the mouse on the "......
                    by clicking here" phrase in order to "activate
                    formatted HTML display"
    Classification: Unclassified
                OS: Linux
          Reporter: sayeed.ka at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kmail2

Application: kmail (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 reading a message in HTML format in Kmail.

2. The raw HTML code was shown as stated in the following note at the start of
the message:

2.1. "Note: This is an HTML message. For security reasons, only the raw HTML
code is shown. If you trust the sender of this message then you can activate
formatted HTML display for this message by clicking here."

3. The user clicked on the "by clicking here" phrase which was highlighted in
blue in order to activate formatted HTML display .

4. At this point Kmail failed and the KDE Crash Reporting Assistant was
invoked.
