Gutsy won't recognise a blank DVD

[Ronnie Tucker]

I burned a DVD this morning yet this afternoon, done no changes to the 
system, Kubuntu won't recognise a blank DVD. I put in a blank and it 
shows me the yellow disc icon on the desktop (no usual window saying 
'what would you like to do with this?') and when I click it Dolphin 
reports (at the bottom of an empty window) the error:

Could not start process Unable to create io-slave:
klauncher said: Unknown protocol ".
.

Even in K3B the disc is not recognised as being valid. Although the 
system can still recognise and play previously burned DVD's no problem.

*sob*

Beginning to think my Gutsy install is falling apart at the seams   :(
