Subject: Convert a Bone to Switch gives two unusable (crasher) Bone Objects.

Add skeleton, right click on a bone of the list, convert to Switch
it provides three parameters:

Link Off: Bone Object
Link On: Bone Object
Switch: bool

Link On and Link Off are Bone Objects in the Value column and the Type column.
A normal (editable) bone is:
Value = Bone's name string
Type = Bone

If you attempt to edit the Bone Object (by double clicking on it) you start
editing a string that fails on:

value.h:240 !'string'.same_type_as('bone_object')
ss-debug: value.h:242: const T& synfig::ValueBase::get(const T&) const [with T = synfig::Bone]: Afirmación `is_valid() && same_type_as(x)' fallida.
