As you can see the Controller is erroneously NULL - since (much like the whole
atk code) it is constructed, but not yet assigned to the parent's member :-)

With my patch I get:

Create dummy accessible for sorter view 0x8fc5658
Create dummy accessible for sorter view 0x8fc5658
Create dummy accessible for sorter view 0x8fc5658
Create real accessible for sorter view 0x8fc5658

which looks more hopeful: also no crash ;-) this follows the comment above that
method which was incorrect: hopefully it was the right general idea ;-)
