Entering Page Content title with quotes causes crash and data loss

What steps will reproduce the problem?
1. Enter a page content
2. Create a second language version of it (Spanish)
3. Enter the page title with some text in double quotes in it

What is the expected output? 
Either accepted page title or error reported.

What do you see instead?
Vosao crash and data loss of the page content entered to date.

Looks like the string entered at the UI prompt is entered directly into the 
JSON string sent to the server for the JSON-RPC:

     {en:"Addit favorite for Internet Explorer",es:"Addit en tu barra de "Favoritos" de Internet Explorer"}

causing a JSON syntax error?

Please use labels and text to provide additional information
Below I enclose a crash log (from App Engine logs) of the crash.....(I have 
removed server hostname and our class names)
