KSysGuard is loaded forever

[Sherif]

If I click ALT+F2 then open KSysGuard, the command window (The rectangle at the top) remains appearing forever at all desktops as shown in Bug1.png and KSysGuard is loaded. If I close KSysGuard, I get error as shown in Bug2.png.
If I open it from start, the whole start bar lags forever as shown in Bug3.png, After closing it, I get the same error as shown in Bug4.png.
Reproducible: Always.

This bug is either fixed by updates or the workaround in comment 5 I applied from bug #1435061. Sorry, I don't know what fixed it.

Should I change it to fix released?
