<p>Easy to reproduce with the following probe:<br><code><br>
xlog("L_NOTICE", "$(ct{param.value,blah})\n");<br></code><br><code><br>
ERROR:core:parse_params: invalid character, ; expected, found &lt;<br></code></p>

<p>This is specific to Contact header only.  Trying to retrieve a bogus param from to or from header does not produce an error in the logs.</p>
