Incomplete text box can be created, thereby corrupting the map so it cannot be recovered.

[GoogleCodeExporter]

What steps will reproduce the problem?
Scenario One:
1. Click somewhere on the map, type some text to create a thought, move the 
cursor to the left, and hit 'Del' to delete some unwanted text.   
2. Ooops, my thought has completely disappeared.  Press Ctl-Z to recover it.
3. Click somewhere else to add a new thought, type some text, press escape to 
close the thought.

Scenario Two: 
3. Click somewhere else to add a new thought, but without typing anything, 
click on the text entered in step 1, and type something, and close the map.

What is the expected output? What do you see instead?

Expected:  The thought from step 1 should be closed; i.e., the box completely 
formed and a link created to the previously selected thought..  Clicking on it 
should highlight it as selected.

Currently:  
Scenario One: The text fragment that was entered in step 1 remains on the 
screen, but it is not possible to select it, close it, link it, or delete it.  
However, it is possible to close the map.  When it is reopened, the thought 
created in step one has been preserved.

Scenario Two: The entire map is corrupted.  It is not possible to reopen it, 
even after completely closing labyrinth.  Attempting to reopen the map returns 
the following python error: AttributeError: 'MMapArea' object has no attribute 
'tree_model'

When a Thought is edited, a delete should now delete characters not the whole 
Thought. Is this helping in your situation?

I can't replicate this, so I'm marking it as fixed.
