Instead of this, I'd recommend just putting the following code snippet
on the lines that you want the breakpoint to exist at:

        $DB::single = 1;

This will cause a break to happen if you're running under the
debugger. 

This is a lot less brittle than hardcoding line numbers.  Also, this
code is harmless if you aren't running underneath the debugger.

Hope this helps,
