            Bug ID: 432421
           Summary: Crash due to signal arriving during destruction of
                    Konsole::SessionController::~SessionController
           Product: konsole
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: kpart
          Assignee: konsole-devel at kde.org
          Reporter: cullmann at kde.org
  Target Milestone: ---

Crash on Kate shutdown, seems a recent thing in master.

Might it be altered connect's? I had similar issues after conversion of stuff
inside Kate to the new C++11 variants, as stuff is disconnected later and
arrives then inside the destructor of your stuff.

Application: Kate (kate), signal: Segmentation fault
