BadStatusLine: '' error on deleting google calendar event from python code - api

Question

I've successfully created and updated the calendar events from python. And the below is my code to delete an event from python code.
def delete_google_event(self, cr, uid, task, user):
g_client = gtools.gcal.google_calendar_interface()
g_client.connect(user.google_email, user.google_password)
g_client.delete(task.google_event_id)
message = "Google event deleted, old id: %s" % (task.google_event_id)
I get the below error when using the above code. From the error message BadStatusLine: '' i understand that i receive a request from the server that system do not understand. But not sure how to solve it. And also the error seems to be with google cal API. Will there be any versioning prob? (i do it in openerp and i guess it's not a problem of openerp)

I've referred this link Why am I getting this error in python ? (httplib). Still not sure of the prob. Kindly give me some clues to fix this. Thanks a lot for your time.

Hurrah!! It works fine in the Direct Connection. But not under proxy.
