Bug: When I change the language of a note from the default to any other, it comes back to the default.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Change the language of a note with "right click > Languages" to any other 
language.
2. Click in any other note.
3. Click back on the previous changed note, the language will be back to the 
default.

What is the expected output? What do you see instead?
The note to be configured with the language I have set previously. But when I 
come back to that note it is back to the default language.

What version of the product are you using? On what operating system?

Please provide any additional information below.
