Application: kscreenlocker (2.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.6.1vin0 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

Resuming from suspend-to-ram, with kscreenlocker set to lock screen.
Running /usr/lib/kde4/libexec/kscreenlocker manually turns the screen plain black (as intended), moving the mouse makes it crash (ie, it does not protect the session anymore).

$ dpkg -l kde-workspace-bin
[...]
ii  kde-workspace-bin                       4:4.8.4-3                amd64                    core binaries for the KDE Plasma Workspace

The crash can be reproduced every time.
