Ubuntu won't recognise usb drive when running KDE. (works under gnome)

[andy baxter]

Hello,

I've just found out that my ubuntu (hardy) system won't recognise my usb 
hard drive when I plug it in since I switched from Gnome to KDE. It used 
to work fine, and now it works only intermittently (I think it works 
when I have had a gnome session running since I last booted, but not 
when I boot straight into KDE). Is this a known bug, and what can I do 
about it, other than manually mounting the drives every time they are 
plugged in?

andy.
