type=radio not working - just me?

[Mable Syrup]

(Ubuntu 10.04)

get_iplayer  --type=xxx works for all except radio, which returns error message:

Worked OK earlier today.  Since then I had to clear out  a .xsessions-errors which had taken up all the free space on the file system, and then I rebooted.  Is there likely to be any correlation?
