https://bugs.kde.org/show_bug.cgi?id=256464

           Summary: Crash inside SSL code
           Product: konversation
           Version: 1.3.1
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konversation-devel at kde.org
        ReportedBy: ehabkost at raisama.net

Application: konversation (1.3.1)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35.6-48.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I asked Konversation to connect to a OFTC through SSL. It didn't know the
server certificate yet, so it has shown the "Cancel/Continue/Details" dialog
for untrusted certificates. I haven't seen the dialog in time, so it stayed on
the screen for a few minutes. When I saw the dialog, the connection was already
lost due to timeout, and when I clicked on "Continue" and then "Forever" on the
next dialog, Konversation crashed.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
82    T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
