Steps to reproduce:
1) Create a new Qt Quick application from the template, choose Qt Quick 2 and a desktop kit in the wizard
2) Ensure that qml debugging is enabled
3) Start debugging
4) In the Locals and Expressions the object tree is shown, select Text
5) In the qml js console enter:
print (this) or print (parent)

I expect both to show the objects and be expandable to show their properties.
See attached screenshot for the result.
