It should be apparent that this affects EFI only. I wouldn't expect secure boot or not to make a difference. Either way, let's hold off on reporting any results on this for a bit.
The only one thing I'm thinking that might be worth testing is whether or not manual partitioning with labels set on all partitions makes a difference. If it does, we at least have a workaround.
Meanwhile kc2bez is testing the fix. Applying to kpmcore alone wasn't sufficient, so we'll rebuild Calamares against that and see how it goes.
