Version: 1.0 (using KDE 4.3.3) Compiler: i686-pc-linux-gnu-4.3.4 CXXFLAGS="-O2 -march=i686 -pipe" LDFLAGS="-Wl,-O1" OS: Linux Installed from: Gentoo Packages Randomly, application's icon remain in the taskbar while processus list (ps aux) don't show them anymore. Right clicking -> Close have no effect. I can't reproduce it as it's a random behaviour.
