Summary. Some value combinations breaks the prevalue editor.

Steps for reproducing this error:

1. Create a radiobuttonlist

2. Create the a prevalue called ") Hello" and save. (Space between ")" and text)

3. Press edit on the prevalues and everything works as expected. You can edit the prevalue.

4. Create a new prevalue called ")Hello" and save (no space between ")" and text)

5. Press edit on the prevalues. You should now see a javascript error like this: "uncaught exception: Syntax error, unrecognized expression: )Hello"

This prevents you from being able to update the prevalues and the only option is to either manipulate the prevalue in the database or deleting the whole radiobuttonlist. Tested and confirmed the same issue on checkboxlists.

Tested on FF and Chrome. Running Contour 1.0.10, Umbraco 4.0.3
