Broken handler for virtual folders?

[Andre Schaefer <a schaefer uni-duisburg de>]

Hello,

I have obviously confused my garnome 2.6.1 installation, esp. nautilus.

I did change the default handler for folders to be rox temporarily.

Then I noticed, this changed behaviour for the virtual location icons 
like computer: as well - they complained that the default handler cannot 
read at computer: locations...

However, settig the default back to nautilus doesn't help, still the 
same error message, although folders open again in nautilus. When I 
direct Nautilus to the virtual location (CTRL-L) then the expected view 
opens. Just clicking on the Computer Icon on the desktop is broken. Same 
for Network:///

Anyone knows how I can revert the changes?
