When trying to 'ls' private bucket, error is returned:
ERROR: S3 error: 403 (Forbidden): SignatureDoesNotMatch
Confirmed in versions 0.9.5, 0.9.8.2.
ls of the same bucket succeeds when using version 0.9.3 with the same keys.
Seems like this happens when the secret key has non-alphanumeric characters (not sure).

What sort of non-alphanumeric characters have you got in your secret key? I've got "+" in one of mine ones and it works just fine. Can you post a debug output (s3cmd -d ls ...), send it to my personal address (michal@logix.cz) if you prefer.
Does the bucket have uppercase letters in the name? If that's the case the problem has been fixed in 0.9.8.4 - you should be able to access your buckets again.
