It seems that the ref was added to all the ports to adapt to the change
in r16803, so that's right. The problem is that the resource handle
should delete itself when there is an error or the load is completed but
that doesn't happen in the CURL backend. Later I will check also the
soup one as it may have the same problem.

Thanks for your report, you saved me time trying to find where the extra
reference should have been added/removed.
