k3b refuses to erase or overwrite a blu-ray rewritable

[Alistair Buxton]

I am trying to write a blu-ray ISO to a rewritable disc which already contains data.

If I try to write the new ISO over the old data, K3B just asks me to replace the disc with a blank one.
If I try to erase the disc, K3B tells me "no need to erase blu-ray rewritables, just write over it."
If I try to force erase the disc, K3B scolds me for doing it, saying "the disc may become unusable after 10-20 formats", and then doesn't erase the disc.

As a result, I can't write the ISO to this rewritable media using K3B.

Note that I have burnt this ISO using this disc and this writer several times using brasero.

Medium->A bug that has a moderate impact on a core application

(I think k3b is probably core, it's in main, and pretty common)

Status changed to 'Confirmed' because the bug affects multiple users.
