Pinta crashes after line draw

[Javier Ignacio Reyes Garcia]

Pinta 1.6 from Ubuntu 18.04 repositories, fresh install.

Steps to produce the crash:

1. Open pinta (tried from desktop, from rofi launcher, and from console

2. Open any image (small, less than 10 kB) from the Open menu (both contextual menu and icon bar).

3. Select the line tool and draw a line on the image.

Result: program crashes. When launched from terminal, this is the output

free(): invalid pointer
