Looks very bad... Is it correct that you need to run it twice. The first
time the file system is ok but after the second time, your file system
is corrupted?

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

Chris Richardson
