Hello Paolo,
please find the stacktrace below. If you need more/other
information, do not hesitate to also contact Jeremy Bicha
<jbi...@ubuntu.com> directly (if you keep 842...@bgus.debian.org in
CC, that would be great).

Thanks a lot for your help!

Greetings

             Helge


It seems a problem in brasero, the relevant goobox code just calls brasero_drive_unlock on a valid brasero drive, that shouldn't crash.

can you provide a stacktrace?

See https://launchpad.net/bugs/1636983

I'm attaching the stacktrace from errors.ubuntu.com . If you need
something different, could you let me know the exact command for me to
enter?

Thanks,
