Bug 353911

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.

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