            Bug ID: 309666
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Kontact starts twice after crash
    Classification: Unclassified
                OS: Linux
          Reporter: jannis at upb.de
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic i686
Distribution: Ubuntu 12.04.1 LTS

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

Before starting kontact I switched from a kdm to a gdm session. I guess, when
starting gdm (which is my standard manager) the former instance of kontact
within the kdm session was (rudely) killed. 

So within the new gdm session I startet kontact again (once!). Then the starter
recognized an already existing instance of kontact. I told it to start another
instance (because no kontact window had appeared). Then kontact started. And
two kontact windows appeared. I closed both of them in order to restart a
"clean" instance afterwards. But before getting that far, the crash report
showed up.

-- Backtrace:
