Notes

mdeslaur

actual bug in bluez, but there is a work-around in gnome-bluetooth https://gitlab.gnome.org/GNOME/gnome-bluetooth/commit/6b5086d42ea64d46277f3c93b43984f331d12f89 gnome-bluetooth <=3.26 used synchronous d-bus calls, so the issue doesn't present itself the bluez patches add new functionnality that newer versions of gnome-bluetooth can use to fix this issue. Since the workaround was applied to gnome-bluetooth, we aren't going to add these commits to bluez. Marking as ignored.
