[Bug 26117] Re: "Shared folders" not working

[Bubbels]

Itś been a while, but i found a good workaround. Use Synaptic to remove the package "nfs-kernel-server". Be sure you do a Complete removal including the config files.
After that, reinstall the same package and you're done. It worked in my case anyway.
As this worked, I suspect there is something wrong in a configuration file.
