Bug Description

There appears to be a bug where-by brasero is unable to eject when it finishes burning. So I do as it says, and eject manually. I then proceed to click finish. However, I attempted to burn something else, and brasero wouldn't open at all. Using the command `htop` (or `top`), I see that brasero is still running in the background. I have to kill the process to be able to continue running another process.

Please note: I'm using Ubuntu 12.04 amd64.

1) $ lsb_release -rd
Description: Ubuntu 12.04.1 LTS
Release: 12.04

2) $ apt-cache policy brasero

3) Brasero to eject the optical medium (CD/DVD) and close gracefully when done.

4) Brasero asks to eject the optical medium manually, and doesn't close the process after clicking "finish".

Just burned another CD, this time from the terminal and using the debug option. Thought this might help a bit.

Also the CD/DVD drive I have (as reported by `hwinfo`) is: TSSTcorp CDDVDW SN-208AB

Command used:

$ brasero ubuntu-12.04.1-desktop-i386.iso -g > brasero-debug.log

Log has been attached. Also note, I had to terminate the command with "CTRL+C" since it was still running.

to blame. :))

Telling from the log, i would say that burning via libburn

But then program readom was started to check the readability of
the finished CD:

> readom dev=/dev/sr0 -nocorr -noerror -sectors=0-355990 -f=-
(Collected from several lines in the log.)

This program run seems not to reach the end of the medium or
at least it does not recognize that it is time to end the program.
The last message is
> BraseroReadom stderr: addr: 355840

That's 150 blocks before the end of the track.


- Try to disable checkreading before you burn.
  (I am not a Brasero user, but the plumber of libburn and libisofs.
   So i cannot tell how to do this disabling.)

- If you cannot disable checkreading, then kill the readom
  process rather than Brasero, when it gets stuck.
  I assume that Brasero will then finish with an error message.

- To learn more about the problem of readom, you could run

    readom dev=/dev/sr0 -nocorr -noerror -sectors=0-355990 -f=- >/dev/null

  and see what it actually reports. (>/dev/null is important to
  avoid that the whole CD content is printed to your terminal.)

Have a nice day :)
