As far as I see, this bug has been always present (if at all) in 1.10.2 as I do not see any info on it. We can try to to apply the suggested fix, but we have no guarantee that it will not break anything along with integration with other hardware and network appliances.
Considering that there is no clear bug description or link to the upstream bug tracker and the implications of such a change are unclear, I suggest to set this bug to high priority and move to 6.1 milestone for further investigation.
