Description smithtrombone 2018-12-12 15:45:29 UTC 
SUMMARY
Upon attempting to use Krita, with a canvas open, with a Wacom Intuos tablet/stylus, Krita will crash with the error "double free or corruption (out)" or "double free or corruption (fasttop)".
I can use Krita with no errors until I open or create a canvas, then Krita will crash as soon as I move the stylus over the window.
I have no special configurations for the wacom tablet and I'm sure the problem is not with the tablet as I can use it with all my other applications without error.


STEPS TO REPRODUCE
1. Open Krita
2. Create a new canvas
3. Move the cursor over the Krita window using the wacom stylus.

OBSERVED RESULT
Instant crash.

EXPECTED RESULT
normal interaction with the Krita UI

SOFTWARE/OS VERSIONS
Arch Linux
no desktop environment (Suckless DWM)
xf86-input-wacom 0.36.1-1

Yes... It's a bug in Qt. I made a workaround today. See QTBUG-72488
