Running `azure site list` raises a TypeError

Steps:

azure account download
azure account import MyFile      (where MyFile is the downloaded publish file)
azure account list               (output is normal and correct)
azure site list
info:    Executing command site list
- Getting locationsinfo:    Executing command site list
+
+ Getting locations
| Getting locationserror:   Cannot read property 'length' of undefined
info:    Error information has been recorded to C:\Users\Me\.azure\azure.err
error:   site list command failed

      

        
        
        
      

    

The file azure.err

looks like this:

Any idea why this is happening?
