Version: (using KDE 4.0.0) Installed from: Ubuntu Packages OS: Linux Steps to Reproduce: 1. Open System Settings. 2. Go to "Keyboard & Mouse" 3. Double-click some entry and expand it. 4. Switch component to Plasma 5. Close the window. Results: At step 4, you get a rendering artifact. At step 5, the application crashes. I don't have debug symbols compiled (Ubuntu), so a backtrace would probably not be useful... here is the console output: systemsettings(6470) GlobalShortcutsModule::componentChanged: Switching to component: "kwin" systemsettings(6470) MainWindow::selectionChanged: adding systemsettings(6470) MainWindow::selectionChanged: adding systemsettings(6470) GlobalShortcutsModule::componentChanged: Switching to component: "plasma" systemsettings(6470) GlobalShortcutsModule::componentChanged: Switching to component: "kwin" ASSERT: "d->extenderIndices.value(extender).isValid()" in file /build/buildd/kde4libs-4.0.0/kdeui/itemviews/kextendableitemdelegate.cpp, line 106 KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = systemsettings path = <unknown> pid = 6470 sock_file=/home/dnasthegreat/.kde4/socket-dnas-laptop/kdeinit4__0
Created attachment 23420 [details] Screenshot of artifacts The screenshot is of the shortcut being expanded on the Plasma tab and switched over to Kwin, but meh... it was taken before I filed the bug; bugzilla seems to hate me.
