Hi Michal

I got the following error while uploading the following file to our ATMOS platform via an S3 proxy:
-rw-r--r--@ 1 glyn staff 3515703296 17 Jul 17:37 Windows8-ReleasePreview-64bit-English.iso

though this file, that was not split, uploaded fine:
-rwx------ 1 glyn staff 649560 7 Jun 16:31 SslvpnClient_4.0.2138.rar

Regards,
Glyn

    I believe this is fixed in upstream github.com/s3tools/s3cmd master branch now.

    commit dd58f170d01d302e19bc7ce23796f929ae8281dd

        Tolerate non-XML errors, e.g. proxy-generated 403/502 HTML errors
    
        Code used to raise an unhandled exception if the resulting error is not an XML
        (ElementTree ParseError when creating S3Error object). In certain cases (e.g.
        5xx errors), this also disrupted the retry flow.
    
        Easily reproducible when running a simple 's3cmd ls' while s3cfg has an http
        proxy set up, and the proxy denies all requests - returns a non-XML 403 error.
    
        * Also extracted a method for the XML Error parsing to clean the code a little.
