Command failed with status (1): [bin/mspec ci -j -t rubinius -B full.mspec...]

The command's failing since the file that will be allocated for the subtend specs (mspec-ci-multi-5) is empty. If I just ignore this set of specs then everything works fine.

The error after running the specs on subtend is:
An error has occured: Bus violation (SIGBUS) (10)

Exception: none

And it's thrown by the specs:
it "rb_check_convert_type should try to coerce to a type, otherwise return nil" do
it "rb_check_convert_type should try to coerce to a type, otherwise return nil" do

These are tagged as failing so I'm not entirely sure why they're being run on CI.
Running shotgun/rubinius /Users/federicobuiles/programacion/rbx/mspec/bin/mspec-ci -fy -B full.mspec -o foo spec/subtend/
by hand works fine.
