This message means that MD could not load the JointUI widget from the
library that implements it. It doesn't matter that you can open the
designer of the widget. This is a run-time error, not a design-time
error.

The most probable cause of this is that the widget is not being properly
exported. There was a bug that was causing widgets to be removed from
the objects.xml file (exported widgets are registered there). In any
case, that file is not needed anymore. Try removing the objects.xml file
and applying the attribute [System.ComponentModel.ToolboxItem(true)] to
all widgets you want to export.

This error seems unrelated to the previous one. Looks like you are
referencing (maybe indirectly, through gtk#) two different versions of
Mono.Cairo.
