I didn't spot an existing bug report when I first filed this but I later found:
https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1635781
...which is pretty closely related. I am using UEFI and Manjaro Linux rather than Legacy BIOS mode and Arch Linux but the cause of the problem seems to be the same.
