[Duplicity-talk] verify fails on 0.6.18 and 0.7.01

[Rupert Levene]

Hi,

I have made a large to gdocs using 0.6.18 from Ubuntu 12.04. A 2GB
file duplicity-full-signatures.20150205T170035Z.sigtar.gpg was
created, and duplicity chokes on this. It pauses for a while (I guess
while it downloads the file) and then says

Attempt 1 failed: BackendException: Failed to download file
'duplicity-full-signatures.20150205T170035Z.sigtar.gpg' in remote
folder 'i7-bigstore': join() result is too long for a Python string
Backtrace of previous error: Traceback (innermost last):
  File "/usr/lib/python2.7/dist-packages/duplicity/backend.py", line
311, in iterate
    return fn(*args, **kwargs)
  File "/usr/lib/python2.7/dist-packages/duplicity/backends/gdocsbackend.py",
line 144, in get
    % (remote_filename, self.folder.title.text, str(e)), raise_errors)
  File "/usr/lib/python2.7/dist-packages/duplicity/backends/gdocsbackend.py",
line 182, in __handle_error
    raise BackendException(message)
 BackendException: Failed to download file
'duplicity-full-signatures.20150205T170035Z.sigtar.gpg' in remote
folder 'i7-bigstore': join() result is too long for a Python string

It'll then try again, and give the same error, at which point I hit control-C.

Version 0.7.01 fails more quickly:

AttributeError: 'DocsClient' object has no attribute 'get_all_resources'

Are these two independent bugs? Is there a workaround or fix?
