[Bug 133257] DVD Recorder hangs after recording

[yS]

Public bug reported:

Binary package hint: k3b

After recording data into a DVD media the DVD recorder hangs. K3b
reports all is OK and the recorded DVD seems to be OK too.

The recorder won't work anymore until I restart the computer. If I press
the eject button... nothing happens. This is the output from an eject
command:

$ LANGUAGE=en eject /dev/scd0 -v
eject: device name is `/dev/scd0'
eject: expanded name is `/dev/scd0'
eject: `/dev/scd0' is not mounted
eject: `/dev/scd0' is not a mount point
eject: `/dev/scd0' is not a multipartition device
eject: trying to eject `/dev/scd0' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/scd0' using SCSI commands
eject: SCSI eject succeeded

Eject says: 'succeeded', but the DVD recorder is still hanged, and don't
react to this. Additionally, here's the output from dmesg. When I put
the disc inside the recorder:

[102448.373887] UDF-fs: No VRS found
[106270.998109] sr0: CDROM not ready.  Make sure there is a disc in the drive.
[107030.110307] cdrom: This disc doesn't have any tracks I recognize!

And when the recording finishes:

Recording works OK with brasero, and worked ok with k3b on versions
previous to 1.0. I wonder what's happening here :|!
