Thanks, you are right, this is a known issue :( There have been patches to address this issue floating around the mailing list, none of them has yet made it up to inclusion. Sam has sent a patch to fix this: https://patchwork.linuxtv.org/patch/52489/ Hugues had something similar I cannot find, if I'm not wrong, and I carry myself the patch I posted in the patchwork discussion in my trees. Feel free to go through the media list and comment. One more report on this would help to increase chances to have one of those patches re-sent and then included. Also, bug reports are always very welcome, but to maximize the chances they receive the required attention, could you make a new email thread next time and drop this one please?
