Cannot delete S3 bucket - permissions issue

Hello, I'm having a problem deleting an S3 bucket (I'm the an admin of the account, without special policy changes)
The error i'm getting is :

If you have s3:DeleteBucket permissions in your IAM user policy and you cannot delete a bucket, the bucket policy might include a deny statement for s3:DeleteBucket. Before you can delete the bucket, you must delete the deny s3:DeleteBucket statement or delete the bucket policy.

Check all permissions and roles again, nothing.
Please advice. I think it's a bug of some sort.
