Hi,

thanks for the patch! :)

This commit is part of the upstream 2.12 release so personally I'd
rather focus on packaging it instead of backporting patches. But if
someone wants to upload this cherry-pick to sid earlier, please
go ahead (and label it "Team upload", no need to call it a NMU).

Cheers,
