#Mint version:
========================
Linux Mint 13 (x86_64)
#What you did for the problem to happen:
==================================
System crashes while saving file from some text editors.
Editors which crashed are: pluma, gedit.
Editors which works fine are: leafpad, libreoffice writer, kate
#How to reproduce it:
==================
The user's home is on nfs4 share (NFS4 server is running freebsd 9). Try to
edit a file or create a new file and save it, the system crashes. Saving it
outside nfs share (eg: /tmp) also crashes the system.
#What happened:
===============
Upon saving, black screen with kernel crash messages are shown. Press "Alt+F8"
to go back to graphical mode. Editor is still running but freezed. Close the
editor and opt "Force quit" to close the editor.
#What you expected to happen instead:
================================
To successfully save the file.
#If the problem happened once, sometimes, or always:
===========================================
Always
