Evan has asked for a call for testing for usb-creator. The mail hasn't hit the archive yet so I am posting it here:
With beta freeze quickly approaching, I have been trying to iron out
the remaining issues in usb-creator, but there have been very few bug
reports to date. If you have a USB stick that you're not using for
important work and have a few moments, I would greatly appreciate it
if you installed the usb-creator package (currently at 0.1.4) and
tested it with an Ubuntu or Kubuntu Desktop CD or ISO file.
Again, I'd like to stress that you should only run this on a disk that
you have or do not need backups of.
Please file any bugs on the source package
