When opening pinta on the command line the app quickly crashes after opening an image and complains about a call to free() erroring out before doing a full memory dump.

It looks like there's another mono configuration issue in the ubuntu 20 image.

The fix is to upgrade mono to the latest:

sudo apt install gnupg ca-certificates
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF
echo "deb https://download.mono-project.com/repo/ubuntu stable-focal main" | sudo tee /etc/apt/sources.list.d/mono-official-stable.list
sudo apt update

You can do mono --version to see if this bug affects you or not. I believe the version that ships with Ubuntu 20 is around 6.8.0.105 from memory. After upgrading you'll see 6.12.0.122 or something similar.
