Unpredictable upload failures

Bug Description

I have a script that automates the process of uploading files for a new release in a project I maintain. It has worked fine in the past, for numerous releases, but it has now become unpredictable and often fails with this error:

Traceback (most recent call last):
  File "./shipit.py", line 409, in lp_upload_file
  File "/usr/local/lib/python2.7/dist-packages/lazr/restfulclient/resource.py", line 607, in __call__

Response body:
signature_content: Cannot upload files larger than 1024 bytes

The files I try to upload are all larger than 1K and smaller than 4MB, and I can manually upload them to the release without problem. The signature content is only 522 bytes. I've tried this both on staging.launchpad.net and the production site.

This is the call in my script that fails:

                        release_file = release.add_file(
                                file_content=open('build/' + filename, 'rb').read(),
                                signature_content=open('build/' + signature_fn, 'rb').read(),
