            Bug ID: 343508
           Summary: Crash (seems to be notification related)
           Product: konsole
           Version: 3.0.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: aacid at kde.org

Application: konsole (3.0.0)

Qt Version: 5.3.2
Operating System: Linux 3.18.0-11-generic x86_64

I was just typing and then the whole konsole went down :/

Backtrace points to notification my untrained eye can't pin point what's wrong

The crash can be reproduced sometimes.
