Unable to download resources with IAM security missing s3:GetAccelerateConfiguration permission

[cyberduck]

After upgrading to 5.2.0.21327 build, I was unable to download resources secured by IAM policies (though I was able to list objects as expected).

I reverted to build 5.1.3.20962 and the downloads worked correctly. I also verified the ability to download via command line tools.

We use IAM policies to secure access to resources by prefix within our buckets. For example, we have a policy like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Action": [ "s3:ListBucket"],
            "Effect": "Allow",
            "Resource": ["arn:aws:s3:::obfuscated"],
            "Condition": { "StringLike": { "s3:prefix": ["more/obfuscation/*"]}}
        },
        {
            "Effect": "Allow",
            "Action": ["s3:*"],
            "Resource": ["arn:aws:s3:::obfuscated/more/obfuscation/*"]
        }
    ]
}

What I end up seeing in the logs suggests it might be the acceleration support added in this build:

Thank you! Sorry if I missed a bug logging this, I tried searching around, but nothing kicked out. And yes, behavior worked as expected in snapshot build - Version 5.3.0 (21327).
