to me how or why the del_uri_param function could be doing this, especially as a transaction hasn’t even been created for the message yet in this case. I’m not sure what effect this would have if the dialog is in other states or at other times during the call.</span><o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-bookmark:_MailOriginalBody"><span style="font-size:11.0pt">It took me a while to realize it was the del_uri_param function causing this, as it seems so strange. But I have verified that when I remove the function, or when
I verify the URI param exists before calling the function, everything is fine. That workaround works perfectly well, but it seemed such strange and catastrophic error behavior to drop the entire message that I wanted to report it anyway to see if anything
needed to be addressed.</span><o:p></o:p></span></p>
