Version: (using KDE 4.2.0) OS: Linux Installed from: Unlisted Binary Package Sometimes (like 1 out of 10 times) KDE 4.2 freezes for 25 seconds (maybe not exactly, just used my stopwatch) when I close a window, that has 'Window shortcut' defined. In particular, I have Meta-W defined for Krusader and Meta-M for Pidgin. As soon as I removed the shortcuts, the problem disappeared (I opened and closed the Pidgin window at least 50 times). I'm using Archlinux with the KDEMod (http://kdemod.ath.cx/about-kdemod.html) repositories. Relevant forum thread (nothing interesting there, just for fullness sake) http://forum.kde.org/sometimes-20-sec-freeze-when-closing-a-window-t-34649.html
The problem persists in KDE 4.2.1
