Back Trace from Cordumpctl and GDB

SUMMARY
This doesn't happen all the time. I can't even say it happens often. More like every now and then. However, sometimes when I turn my monitors off and back on. Dolphin crashes. I remember the last time having three dolphin windows open and when I turned my monitors off and back on. Two of them crashed, but the third remained open.

STEPS TO REPRODUCE
1. Open dolphin.
2. I have two monitors, but not sure if that is necessary, Anyways, I usually turn them both off at the same time. As in, I try to press the power button on both of them at the same time. Not sure if that plays a roll.
3. Turn them back on.

OBSERVED RESULT
Dolphin sometimes crashes.

EXPECTED RESULT
It should never crash.
