            Bug ID: 308580
          Severity: crash
           Version: 4.9.2
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Crash in KManageSieve::Session
    Classification: Unclassified
                OS: Linux
          Reporter: dvratil at redhat.com
          Hardware: Fedora RPMs
            Status: NEW
         Component: general
           Product: kontact

Application: kontact (4.9.2)
KDE Platform Version: 4.9.2
Qt Version: 4.8.3
Operating System: Linux 3.6.1-1.fc18.x86_64 x86_64
Distribution: "Fedora release 19 (Rawhide)"

-- Information about the crash:
- What I was doing when the application crashed:
Not sure if it's related, but I was prompted about invalid/untrusted server
certificate (which is OK, I only have a self-signed certificate on my server).
After confirming the exception and confirming to always trust this certificate,
Kontact just crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
