pcbnew crashes when creating any fill boundary

[Paul Hansel]

On any .kicad_pcb file, pcbnew (6.0.0-rc1-dev-84-g93c173f) crashes with a failed assertion dialog box on the first point of a fill/pour outline. "Continue" and "Stop" both result in a segfault.

ASSERT INFO:
../src/common/datavcmn.cpp(641): assert "variant.GetType() == "wxDataViewIconText"" failed in operator<<().

Seems like I have the same problem. I first encountered this when trying to define a keep-out area, but it also happens when trying to edit a fill area.

I am on Ubuntu Bionic
