Random Error was created by snowgoer540
Today QtPlasmaC crashed for no apparent reason (it was just sitting idle).
This was the error associated with the crash:
I did have Designer open, and closed it and closed without saving changes. I can't see what the correlation would be, but I received the error message in QtPlasmaC right around the same time. I did try to duplicate the scenario, but to no avail.
The error seemed to be random. Not sure if it needs an exception, or what could be going on?

That is hard to say what happened. I bet it was caused by the closing of designer but it might be a race condition, so hard to trigger.
I could trap the error to print something then we might get more info in the long run.

Saw you pushed a trap as mentioned. Thank you, I will keep an eye out if I see the error again and report back if there is any information that comes out of it.
Probably a 1:1,000,000 condition. Those are the worst.
