Comment 0 for bug 1840480

I open it and start working. Everything seems fine but after a couple minutes (and some times less) it crashes. It happens only if I really work - if it just stays opened and I do nothing then nothing happens. I tried update & upgrade & reboot. I've recently upgraded from 16.04 to 18.04 and haven't used pinta scince the upgrade, so it can be something with it. After the crush I get this in the terminal:

$ pinta
free(): invalid pointer
