However, if I change line 951 from:

if (src->session_io_status == GST_SOUP_HTTP_SRC_SESSION_IO_STATUS_IDLE) {

to:

if (TRUE) {

seeking works *if I do not seek ahead too quickly*.

Somewhere along the way src->session_io_status is not being put in the correct
state. Or, src->session_io_status is not an proper way of deciding.

Does this happen every time?
