Version: (using KDE 4.0.4) Installed from: Ubuntu Packages OS: Linux I've found a repeatable bug in systemsettings. Steps to Reproduce: ******************** 1. Open systemsettings 2. Double Click 'Keyboard and Mouse' 3. Click the 'Keyboard Shortcuts' item in the left sidebar 4. Double click on one of the listed shortcuts 5. Change the 'KDE Component' selection above to another item 6. GLITCH SHOULD BE VISIBLE 7. Double Click another shortcut. 8. It should crash here. Expected behaviour: ******************** It should not crash
cannot reproduce on r809608
Also cannot reproduce, r810995.
@Ellis: on the sixth point you write about glitches, could you post a screenshot? Moreover if you can reproduce the crash you should post the backtrace following the instruction on: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports (remember that backtrace without debug information are useless). Thanks

Screenshots of graphical glitch attached. systemsettings-glitch-1 shows the glitch. Basically, I expanded the 'Block Global Shortcuts' dropdown, then changed the KDE component to 'plasma' systemsettings-glitch-2 shows the glitch after switching back to 'kwin' as the KDE component. Following these two steps, I can crash the desktop in two ways: With Desktop Effects, it crashes if I dbl-click 'Block Global Shortcuts' again. Without desktop effects enabled, it crashes after the window is closed. I will provide backtraces with proper debug information after the -dbg libraries are installed. I have a poor connection, so I was hoping someone else could reproduce and post the proper info...

I fixed this on trunk. I guess it is part of 4.1. *** This bug has been marked as a duplicate of 154647 ***
