Bug 513346

SUMMARY
I used a script to turn off the screen, which previously worked without issues. The script is as follows:

#!/bin/sh
/bin/sleep 1 && /bin/dbus-send --session --print-reply --dest=org.kde.kglobalaccel /component/org_kde_powerdevil org.kde.kglobalaccel.Component.invokeShortcut string:'Turn Off Screen'

However, I discovered that if I run this script in Konsole and interrupt it by touching the touchpad while the screen is dimming, KWin throws errors and freezes. After the system enters S0ix sleep and wakes up, KWin recovers. Checking the journal reveals a large number of repeated errors.

STEPS TO REPRODUCE
1. Run the script in Konsole.
2. Interrupt the process by touching the touchpad while the screen is dimming.
3. KWin freezes and throws errors.

OBSERVED RESULT
KWin freezes and throws repeated errors. Below is a sample of the log:

And these logs repeats again and again...

EXPECTED RESULT
KWin should not freeze when the dimming process is interrupted by user input.
