If this is an inappropriate location for the submission of a bug report with patch against the master branch of the git repo for parley, then please inform me and I will submit it in the appropriate location.

Bug Report:  

1. Start Parley
2. Create New Collection. 
3. Click OK
4. Add Language.
5. Download new grammar.  (for the new 3rd language)
6. Crash.


Add a new identifier to the kvocdoc if there are fewer languages that the requested number.
Repeated the above steps and no crash.
