Bug 896657

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

urlgrabber resets the curl object between requests, and this clears CURLOPT_ERRORBUFFER, so we don't get any more info than errcode == 35.

The error handling could be changed, and we could probably work around the .reset() part by creating new curl object for every request.

Originally, this was fixed upstream with:

commit 129e0e9833ad9458acf599f29392214071e1f3b5
Author: Zdenek Pavlas <zpavlas>
Date:   Wed Mar 27 10:43:29 2013 +0100

    curl_obj.reset() is the only way to reset HTTP ranges, revert to it.  BZ 923951

However, we later reverted to resetting curl_obj again because of another bug:

commit 6c07f3ddc58c02a662d3be3133b95a43d5af48b8
Author: Zdenek Pavlas <zpavlas>
Date:   Fri Jan 18 10:57:46 2013 +0100

    URLGrabError(14) cleanup.  BZ 896657
    
    Work around a pycurl bug, so error details are available again.
    Remove all but one code paths that were raising URLGrabError(14),
    and throwing error details away.

Which makes the original commit ineffective.

Oops, actually the commits were the other way around :)
