NetVault GUI crashes in RHEL/CentOS 6.X (4047629)

Running nvgui on the console fails, although using ssh -X to login from another server, the GUI does run.

System error displayed is:

Jun 7 16:38:25 localhost kernel: nvguidisplay[3249]: segfault at 24

Legacy X Windows libraries are required to run the NetVault GUI.

Run the following command to install the required packages.

sudo yum groupinstall "Legacy X Window System Compatibility"

Note: In NetVault Backup 11 and later all X11 GUI's have been removed.
