Calendar Batch Modifications cause Error 400 Bad Request

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Create batch object
batch = BatchHttpRequest()
2.Retrieve primary calendar 
calendar = service.calendars().get(calendarId='primary').execute()
3.modify calendar 
calendar['summary'] = 'New Title for calendar'
4.add update request to batch
batch.add(service.calendars().update(calendarId=calendar['id'],
                                                 body=calendar))
5.Execute Batch
batch.execute()

What is the expected output? What do you see instead?
I expect that the execution should modify the primary calendar's name to the 
new assigned value. Instead a HttpError is thrown with Error Code 400, saying 
BadRequest.

What version of the product are you using? On what operating system?
Version 1.0beta7, Ubuntu 10.04

Please provide any additional information below.
A similar result happens on insertions like creating a new calendar. For 
requests that do not modify anything, like service.calendarList().list(), it 
works as expected.
I have only been working with the Calendar resources.

Do you get errors with the calls that make modifications when not made in batch 
calls? That is, if you don't use batch do all the calls you are making succeed?

Yes, when making calls like service.calendars.update(calendarId=calendar['id'], 
body=calendar).execute(), it works as expected.

Currently being investigated, looks like an issue on the server side and the 
client side. Client side issues have been addressed in

a7935a639e51707c7bde9314e8 but batching is still broken for mutating requests.

There was just a push to prod that fixed this issue.

There is still one outstanding issue with batch:
