Full stack trace

I've hit this NPE when executing the follow XML schema editing scenario:
- create a new XML schema file with the New XML Schema wizard
- go to the graphical view
- select the elements compartment in the top level index figure
- right click and add a new element
- click away from the direct edit box to finish adding 
- select the element
- right click and choose remove from the context menu
- go to the source view
- the cursor should be right before the schema element's opening tag angle bracket
- hit Ctrl+Shift+F to format the document
- note the NPE

Here's part of the stack trace (see attachment for the full trace):
