Pinta crash after layers uncheck and paste

[grofaty]

Pinta/master/github on Ubuntu 20.04.

1. Layers pad. Click on layer to uncheck the layer.
2. <Ctrl>+<Print Screen> actually Ubuntu shortcut to copy image into clipboard.
3. <Ctrl>+<Alt>+V to paste image from clipboard to new image in Pinta. PROBLEM: Crash appears with error:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
   at Pinta.Gui.Widgets.CanvasRenderer.Render(List`1 layers, ImageSurface dst, Point offset)
   at Pinta.Gui.Widgets.PintaCanvas.OnDrawn(Context context)
   at Gtk.Widget.Drawn_cb(IntPtr inst, IntPtr cr)

Retested in Pinta 2.0.2 on Ubuntu 20.04 and crash already appears, so no regression in master.

I could repro this, although my stack trace looked a bit different
Should be fixed by https://github.com/PintaProject/Pinta/commit/c9a4cb5b81aad1a6b53e4b68ad52f45e220d8df1

Retested in today's Pinta/master/github and can confirm this problem is fixed. Thanks.
