[Bug 41682] CD burner does not respect burn speed?

[Sitsofe Wheeler]

Public bug reported:

Affects: nautilus-cd-burner (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Description of the problem:
I have some flakey disks that I can only burn at double speed even though they are rated at 4 speed. Consequently in any cd burning program I use I have to ensure the speed is no higher than 2 in order to use them.

However when I try and use nautilus burn it myseriously is unable to blank or burn anything to these disks (and I can see the light on the drive flickering on and off as it does when the speed is too high). If I manually use cdrecord then I can both blank and burn at speed 2. I suspect nautilus-cdi-burner is quitely ignoring my setting of speed 2 and instead trying to go as fast as it can. This is not easy to check though because nautilus burn no longer shows meaningful diagnostics when it fails instead resigning itself to saying:
Error writing to disc
There was an error writing to the disc

Steps to reproduce:
1. Insert a rewritable CD that claims it can be burned to faster than it can at a speed our drive can cope with.
2. In nautilus go to Places -> CD/DVD Creator .
3. Drag a small file to be burned into the CD creator window and press write to disk.
4. Change the write speed to 2x.
5. Click on Write.
6. (If CD isn't blank click on the Erase Disk button in the window that appears)

Expected results:
All CD burning actions (erasing, writing of image) to happen at the slower speed.

Actual results:
All CD burning actions (erasing, writing of image) seemingly happen at the Maximum Possible speed.

Additional Informatin:
CD burning no longer gives enough detail on errors.
