aws dynamodb put-item dies with `No module names _parseaddr`

[foretspaisibles]

I am populating to DynamoDB table for testing purposes. In a local instance, I prepared a table Music as in the tutorial. Inserting item with aws dynamodb put-item dies unexpectedly with the message No module names _parseaddr after 433 succesful insertions.

This is, by the way, not reliably reproductible. I had it again after 716 insertions.

@michipili Do you have an email module installed somewhere on your system? This appears to be a relatively common issue with requests (the http library we use), though it's strange that it is so intermittent.

[foretspaisibles]

Superficial research shows that it is common issue for many Python products. The oldest reference I could find refers to Python 2.4. It seems that this is not related to aws cli itself bu rather with Python, so we can close this issue.
