Cannot create map frame in cartographic composer

[cmbarton]

Because the button to save a display to an image file is also broken, there is no way to export a map from GRASS. So I'm elevating both bug reports to blockers. This is broken in at least v. 7.4.1 and up.

I can draw a dotted line rectangle but it does not create a map frame. So nothing else works in the composer.

Here is the error:
