Yes, the libuuid.so bug would be a likely suspect. If the UUIDPlugin was
built as an external library, just delete it and you will probably be
good to go.

If you need further info, look here:

I am fairly certain the vm is 'Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.54]' (can verify later today), but this happened with an earlier Cog one-click too.  There is something about the machine (UUID again?) that is different.  I do not have root access to it, but I can get to a terminal.  Ubuntu 10.10.

The Cog one-click image crashes with "Segmentation fault" (if run from a terminal); the legacy VM seems to run the image nicely on the box.  Any ideas?  I will happily collect any facts that will be of help, but I need some
