Kubuntu Bugette? Mount Icons on the desktop

[Adam McGreggor]

Hum, bit of a bugger this one, which I can't work out where things are
going wrong (these graphical things!).

With nfs mounts working fine through points; (I've tried with fstab
entries, and mount(8) on the command line.

But on the 'Desktop Configure' / Behaviour / Device Icons, with 'Mounted
NFS Share' selected, the icons still aren't showing up on my desktop, as
they should; I can't see anything unexpected in ~/Desktop/.directory

Thoughts on how to get the icons to show? 

Is there somewhere else I should be looking? -- changing 
~/.kde/share/config/kdesktoprc's [Media] section doesn't have any effect.

TIA,
