pinta crashes with rectangular selection

[Danilo Balarini]

I'm on Ubuntu 17_04 and pinta -version = 1.6

I have dual monitor, took a print screen and tried to use rectangular selection on it with pinta. When using it, while dimensioning, it stops and crashes.

This is what the console prints. The image is attached.
