Yes I have automatic screen locking enabled.

No that was a first wrong impression. Cancel actually crashes the whole thing. 

There is a particularity that makes that you can open the new session with the
applet without crash. 
Now that works in this complicated way:
Open the first session A.
lock the session with the screen saver and open a second session B.
Now wait until the automatic screen saver pop up. Now unlock B.
You will now be able to open a new user session C with the applet. 
But in this new user session C, if you try the applet it will crash the very
session C.
Now comes the best: once the third session has crashed, you find yourself again
at session two (B). Now if you try to open again with the applet the new user
session C, B will now crash immediately. 
This is repeatable, always on this system. 
The session A will be still usable and will not have crashed. 

Hope that was understandable somehow.
