 This crash seems to happen because the newly created project has no Cabs AST.
Possible fix: provide a way to signal the absence of Cabs in projects.

SVN revision 15057 renders message output clearer (Kernel.fatal "bad initialisation" and Ast.Bad_Initialization produced much too similar output) , catches this fatal message in the Metrics plugin, and tries to give a possible explanation. The suggested fix above should will probably mitigate this need.
