There is a roundup bug with patch for that.
The issue is that some code uses url_read instead of url_read_complete,
at least in some cases with http that means the code ends up using
unintialized data and worse that uninitialized data will even appear
in addition to valid data so not even the file offsets make any sense
anymore (at least it looked like that to me, though the first part
alone is bad enough).
