Bug 363990

Application: ksnapshot (0.8.2)
KDE Platform Version: 4.14.18
Qt Version: 4.8.6
Operating System: Linux 4.1.21-14-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
With capture mode "Window under cursor" and click on background, kstanpshot crashes, and it kills window manager as well. It is then no longer possible to bring up selected window from the taskbar, save work, start new programs, reposition windows ... desktop session is practically useless and needs to be restarted.

The crash can be reproduced every time.

-- Backtrace:
Application: KSnapshot (ksnapshot), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
