I tried to reproduce the original bug without success -- I am able to burn a CD with names containing spaces without a problem. I checked the version numbers of the packages installed, and most of them seem to be the same (brasero, wodim, genisoimage). The only one that has changed is libnautilus-burn4, but I am unsure if this is actually involved in this operation.
Now that I take a closer look at the mentioned Gnome bug (#490853), I see that Joliet compatibility seems to be required for the bug to occur. In the test I just made, I paid no attention to that checkbox, but a quick trial shows that this is enabled by default. Thanks Alan and Sven. As far as I am concerned, this bug can be closed. -- Alvaro Herrera Valdivia, Chile ICBM: S 39º 48' 55.3", W 73º 15' 24.7" "When the proper man does nothing (wu-wei), his thought is felt ten thousand miles."
