            Bug ID: 353911
           Summary: Konsole crash on receiving focus
           Product: konsole
           Version: 15.04.0
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kenaaker at gmail.com

Application: konsole (15.04.0)

Qt Version: 5.5.0
Operating System: Linux 4.2.1-1-desktop x86_64
Distribution: "openSUSE Tumbleweed (20151002) (x86_64)"

-- Information about the crash:
I had several console windows open. Focus follows mouse. Moving the mouse
through a konsole window caused all the konsole windows to crash and disappear.

The crash can be reproduced sometimes.
