Public bug reported:

Description of problem: When downloading a glance image while adding --progress  I get an error:
object of type 'generator' has no len() 

Same command without --progress works fine.

Version-Release number of selected component (if applicable):
rhel7

python-glanceclient-0.14.2-1.el7ost.noarch
python-glance-store-0.1.8-1.el7ost.noarch
openstack-glance-2014.2.1-2.el7ost.noarch

On Icehouse ( python-glanceclient-0.13.1-1.el7ost.noarch 
) it works fine, just checked it now.  

How reproducible:
Every time, on two separate deployments 

Steps to Reproduce:
1. Upload image to glance
2. glance image-download <imageID> --file test.raw --progress - fails 
3. Do same without --progress works fine.

4. Also tested with a snapshot of an instance as source same error.

Actual results:
# glance image-download c3d3f.... --file cirros2.raw --progress
object of type 'generator' has no len()  

Expected results:
File should download without error and with progress bar indicator
