Hi Trond,
Out of curiosity, what entry do you have in /etc/auto_master?
The default is:
/home auto_home -nobrowse
directories in /home are only visible if they've been specifically requested,
but if you don't have nobrowse, it's possible that in getting the full tree to
represent in a tree-view in nautilus it's trying to see what dirs it has access
to, etc.
It also looks like (because of port_associate calls) that nautilus is actually
monitoring these dirs for change too - but I could be mistaken without looking
at the code.
Darren.
