/cc @bajtos - seems to have been introduced in 5db936d.

See the pull request for a fix.

This is the behaviour before 5db936d (which was BTW back-ported to v0.10 as a32a243):

$ node -v
v0.10.5
$ node debug -p $(pgrep node)
connecting... ok
debug> setBreakpoint(100)
Script : undefined not found
debug>

Seems to have been resolved.
