I have found/mentioned this myself.
When the CD is detected it is automounted, icon on desktop/filesystem 
folder. There is a right-click item to eject, but not unmount.

I needed to: umount /dev/cdrom manually so that it wasn't locked for 
writing, and also not ejected from the machine. Then k2b worked fine.

I was hoping that this would be cured, but I can repeat it now, with 
identical results: erase fails, and I get stuck in a loop where I cannot 
exit the k3b erase dialogs.
