Exception when resume from breakpoint

In Atom,

open samples/general/hello.dart
set 3 breakpoints
select hello.dart in the run app dropdown
click the gear to the left of the run app dropdown
add debug: true under dartino: in the hello.yaml file to enable debugging for this app
run hello.dart in Atom
when you hit a breakpoint, click the resume button.

On the 2nd resume, this exception occurs...
