Please can you capture a backtrace by running it under gdb. Valgrind might
also have something interesting to say.

FWIW this doesn't happen on the current development branch:
    # cat foo
    Testing
    # xl cpupool-create foo
    foo:1: config parsing error near `Testing': lexical error
    Failed to parse config file: Invalid argument

But I don't see any obviously related looking fixes in the commit log.

Was 4.5.0 ok?
