Dear Pharo users on Ubuntu, there was a problem with the VM embedded in the ubuntu packages on the PPA (https://launchpad.net/~pharo/+archive/stable/).
This bug has been solved! The bug was in the VM source code which has been fixed by upstream. Best, -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." Winston Churchill
