Version: (using KDE 4.4.0) Compiler: GCC 4.4.3 OS: Linux Installed from: Archlinux Packages I saw this article related to Gnome's screenlock being broken: http://www.h-online.com/security/news/item/GNOME-screen-lock-ineffective-in-openSUSE-Linux-Update-928794.html Using KDE 4.4 I can reproduce the same behavior. Using several different screensavers, including the blank screen mode, and with compositing turned on or off it is possible to crash the screen-lock program simply by pressing enter. Steps to reproduce: 1. Lock the screen 2. Press <enter> several times. Pressing & holding is also effective. The screen lock does not always fail immediately, but in less than a minute this bug is 100% reproducible and allows access to the desktop. 3. Other keys may help crash it as well, but I only need to press enter to reproduce the bug. Suggested Solution: Trap input events better so that the program cannot crash. Institute a timer so that there is a delay between when the program will accept user input.
