Perhaps it is possible to reproduce it on a virtual machine?

What are the steps to reproduce it? Could you make a very test
program?

Failed X connection corrupts root filesystem

Bug description:
I noticed this problem a while ago, and just fell victim to it again this morning.

I was doing a dolfin install from bzr as root on Ubuntu Lucid 10.4 64-bit server.
When running a demo, if the X forwarding is not correctly set, then the code crashes in a plot() call, with a PETSC error. Subsequently, the root file system is severely damaged, and the only option seems to be a complete reinstall of the OS.

I know, this can be avoided by not running the demos as root, but it is an easy mistake to make after doing a system-wide install.
I presume it is a bug in viper.

Any ideas?

Thanks
