Apparently Lua 5.1 has changed the semantics of table.insert so it's incompatible with the way used in all Auto3 demo scripts etc. Now it's overridden in utils.auto3 and all instances of it in sample scripts etc. replaced with code having the expected behaviour. Originally committed to SVN as r926.
