Possible Problems with ga.read_ga
Hi, 

I have a python script that runs on a daily basis and I noticed a problem this morning with the ga.read function. Nothing has changed with my GA account and I have not touched the python script. I've attached the error message below:

``` python

I currently use Pandas v 0.11.0 (numpy 1.7.1) but I have tried uninstalling and reverting back to 0.10.1 just in case (didn't think this would help!) - Is it failing to pickup details associated with my account? In the above I have commented out my hardcoded account_id as i have never had to submit this before.

I have also tried the same query in the Google API Query Explorer and it still works fine. 

This is my first post on github and I am a python beginner so please forgive any obvious mistakes.

Thanks

Dan
