As a note, it looks like google changed its webpage for recent calls and messages (as I was testing before prepping for a new release, good timing). I've got a fix in 1.0.3 which is going to be packaged soon. *sigh* Usually I give more descriptive errors than an empty string. The lack of descriptive errors is hopefully fixed in 1.0.3 which I'm working on. Hopefully that'll help in figuring out what the real issue is.
