Hi Laurent,

Thanks for the update. I added this to the Mantis 7358 issue also.

I have one more request if you have the time. Could you please download
Ian's latest build to your system, and try running the Pharo test using
Ian's build? The reason that I ask is that neither Ian nor I can reproduce
the UUID bug on our computers.  So if you can run Ian's VM on your computer
without problems for the UUID bug, this would indicate that it is safe
to distribute the VM with the internal UUID plugin for Squeak users.

You can download the VM from:

You do not need to install Ian's VM to test it, just unpack it into a
temporary directory, and run it from the temporary directory.

  $ tar xzvf Squeak-
  $ cd Squeak-
  $ ./squeak ../../pharo.image

Thanks a lot, this is a big help :)
