In spite of successful burn: "GError: Error while writing to disc. Try a lower speed."

[Piraja]

Binary package hint: serpentine

1) CrunchBang Linux 8.10 (based on Ubuntu Intrepid)
2) 0.9-5ubuntu3
3) Burn a CD-R at 4 x speed.
4) In spite of successfully burning the CD, I get the error message: "GError: Error while writing to disc. Try a lower speed." This is always reproducible, i.e. happens every time. A minor issue, but I thought it still worth reporting.

Hardware: Philips JackRabbit JR4DVDRW external DVD+RW drive.

Terminal output:
