Fetching ETAG fails if filename contains whitespace

[janpieper]

require "aws-sdk"

s3_client = Aws::S3::Client.new({
  :access_key_id => "...",
  :secret_access_key => "...",
  :region => "eu-central-1"
})

s3_bucket = Aws::S3::Bucket.new(
  name: "...",
  client: s3_client
)

s3_bucket.objects(prefix: "files/").each do |object_summary|
  puts object_summary.object.key
  puts object_summary.object.etag
end

Calling #key works fine, but if you call #etag an Aws::S3::Errors::NotFound error will be raised.

Thanks for reporting the issue! I've corrected the unit test that was covering this and added an integration test to exercise this against Amazon S3.
