Ejecting a Blanc CD/DVD/BluRay-R disk writes to it.

[Guillaume Bottex]

I used the "eject" contextual menu on the icon of a blank Bluray-R on the caja desktop, and I got a message saying that I need to wait for data to be written on the disc before being able to remove it safely (same message as when trying to eject an usb stick, when some data syncing is left to be done).

Afterwards, when I tried to burn data to it, the app (k3b) told that the disc was not empty thus not writeable.

This bug cost me a brand new Bluray-R M-Disc of 100GB, which is a quite pricey medium.

Thank you for the bug report, could you add the 'journalctl -b <n>' from the session where you had the issue? It's unlikely that udisks wrote to disk though

Here it is

[Sebastien Bacher (seb128)]

the log indicates there was a segfault, did you get a report created for udisk in /var/crash/ ?

systemd[1]: udisks2.service: Main process exited, code=killed, status=11/SEGV

Unfortunately, I don't have any crash report for udisk in /var/crash.
