  * Does the problem affect deployed apps?
  --- Apps running in the development server

* If you are having problems with the SDK, please tell us about
the SDK that you are using:
* version
    --- 1.9.18 - 2015-02-18
* language
    --- PHP
* operating system
    --- MAC OS X

  * How can someone else reproduce the problem?
  --- In Chrome and Firefox, when one has an <audio> or <video> object on a page via , a "Range: byte=0-" request header is sent to retrieve the file. It seems the dev_appserver.py server is failing on an index out of bound error. Note that the video or audio file is being served from GCS via CloudStorageTools::getPublicUrl(). Also the issue doesn't occur with Safari, as its request headers are different.

* What is the expected output?
  --- a 200* type http response with the <audio> or <video> object loaded with the file ready to play.  
* What do you see instead?
  --- <audio> or <video> component cannot play the file. Checking the server logs you see the following:
  ERROR    2015-03-05 06:54:51,474 module.py:821] Request to '/_ah/gcs/app_default_bucket/54f7f198c0ada17254747324.wav' failed

On an older SDK, the error print out is more instructive:

ERROR    2015-03-05 07:30:59,347 module.py:717] Request to '/_ah/gcs/app_default_bucket/54f7f198c0ada17254747324.wav' failed

***while writing this issue, I decided to look further into this and provide a fix. Seems that Chrome and Firefox doesn't set the Range header properly. They set it like, Range: bytes=1-0, when doing a <video> or <audio> tag.

Fix is for the _Range class in stub_dispatcher.py:

class _Range(_Header):
  """_Range header.

  Used by read. Format: Range: bytes=1-3.
  """

  HEADER = 'Range'

  def __init__(self, headers):
    super(_Range, self).__init__(headers)
    if self.value:
      start, end = self.value.rsplit('=', 1)[-1].split('-')
      if end == '': # cR - the fix
        end = long(start) + 1 # cR - should this be bounded/limited - security issue???
      start, end = long(start), long(end)
    else:
      start, end = 0, None
    self.value = start, end

Not sure if the above is good python. Haven't used it in a while. Please could this be fixed in this or in the browser. Moreover, for production purposes, we'd definitely need this working.

Thanks a mil!
