org.json.JSONException: JSON does not allow non-finite numbers.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new project from the attached CSV file.
2. Reconcile the first column using FreeBase reconciliation service and type 
/music/track
3. Export -> Export project

What is the expected output? What do you see instead?

Exported project can not be loaded back into Refine. A "org.json.JSONException: 
JSON does not allow non-finite numbers." is printed in the console while 
exporting.

What version of Google Refine are you using?

trunk@2029

What operating system and browser are you using?

Debian Squeeze, Firefox 3.5.16

Is this problem specific to the type of browser you're using or it happens
in all the browsers you tried?

Not specific.

Please provide any additional information below.

Please find attached a patch that appears to solve this problem. The problem 
appears because the string being reconciliated only contains stop words. In 
that case wordDistance() method returns NaN, which can not be serialized into 
JSON.
