Application: kcmshell4 (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.4-ck2-kubuntu-amdf10-rjvb x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I had made some modifications to my kwallet settings. When I hit the OK button, an authorisation dialog was presented, as expected. By mistake I hit the OK button another time, and proceeded to enter my password in the dialog. I am not sure if the kcmshell window disappeared (and the crash reporter appeared) before I finished entering my password or only after wards.
