This was a tough one. When upgrading from Sarge to Etch OpenOffice 2.0 was installed. After the upgrade I was not able to save files to NFS shared drives.
The solution seems to be to install nfs-common. More information
here For me it worked.
I am just surprised that nfs-common is not a part of the nfs-client package. Anyway, it seems to be solved now.
(Also do not forget to install openoffice.org-kde. If you don't the menu fonts look
real ugly.
