Segfault when URI path is empty

[TBRTechSAT]

Using the following script I get a segfault when executing the send statement (using HttpEventProcessor

<?xml version="1.0" encoding="UTF-8"?>
<!-- Test BasicHttpEventProcessor.
     This script sends an event every second to another
     scxml executor instance. -->
<scxml datamodel="ecmascript"  xmlns="http://www.w3.org/2005/07/scxml" initial="start" version="1.0">
    <state id="start">
        <onentry>
            <log expr="'send the event wakeup to http://localhost:56789'" />
            <send event="timer"  delay="1s"/>
            <send event="wakeup" type="http://www.w3.org/TR/scxml/#HTTPEventProcessor" target="http://localhost:56789"/><!-- empty path -->
        </onentry>
        <transition event="timer" target="start" />
    </state>
    <final id="end">
    </final>
</scxml>

Here is the patch containing the changes that I used to fix the issue:
