Description
Hello,
Trying to list the blobs of a container in an azure blob storage, the instanciation step of a container systematically breaks with a 400 bad request.
I have not much details in the error message:
Traceback (most recent call last): File "./bin/basic-scenario", line 20, in <module> container = driver.get_container(container_name=container_name) File "/usr/lib/python3/dist-packages/libcloud/storage/drivers/azure_blobs.py", line 441, in get_container (response.status), driver=self) libcloud.common.types.LibcloudError: <LibcloudError in <libcloud.storage.drivers.azure_blobs.AzureBlobsStorageDriver object at 0x7f674c6b67f0> 'Unexpected status code: 400'
Here is the code of ./bin/basic-scenario:
#!/usr/bin/env python3 from libcloud.storage.types import Provider from libcloud.storage.providers import get_driver if __name__ == '__main__': # setup account_name = 'account-name' key = 'secret-key' container_name = 'container-name' # libcloud setup cls = get_driver(Provider.AZURE_BLOBS) # this instanciates ok driver = cls(key=account_name, secret=key) # this explodes container = driver.get_container(container_name=container_name) for c in driver.iterate_container_objects(container): print(c)
Trying to dig in the error, using LIBCLOUD_DEBUG:
LIBCLOUD_DEBUG=error-output ./bin/basic-scenario
I have some more input, here is the content of error-output file:

As my package is a debian one with what seems an older version (0.20.0, seen in CHANGES.rst and not in the propose jira list), I tried with the current git repository (1.1.0).
Procedure:
1. purged python3-libcloud from my machine
2. `python3 setup.py install` from git repository.
I have the same error:
# -------- begin 139921458559016 request ---------- curl -i --head -H 'x-ms-version: 2012-02-12' -H 'Authorization: SharedKey account-name:blabloblu=' -H 'X-LC-Request-ID: 139921458559432' -H 'User-Agent: libcloud/1.1.0 (Microsoft Azure (blobs)) ' -H 'Accept-Encoding: gzip,deflate' -H 'x-ms-date: Fri, 09 Sep 2016 10:51:53 GMT' --compress 'https://account-name.blob.core.windows.net:443/container-name?restype=container' # -------- begin 139921458559016:139921458672360 response ---------- HTTP/1.1 400 The value for one of the HTTP headers is not in the correct format.

I'm stuck there since i don't see anything wrong with the headers.
Do you please have some hint?
Thanks for your time
Note:
- I'm confident in the azure blob storage setup and credentials since i got it working with another library (azure-storage via pip3)
