[reSIProcate] assert in sendToWire

[Daniel Pocock]

On Saturday, I updated to the latest version of reSIProcate from SVN (6901).

Since then, I've been getting this assert() occasionally:

   else // reuse the last dns tuple
   {
      assert(sip->isRequest());
      assert(mTarget.getType() != UNKNOWN_TRANSPORT);  // line 1761 ****
      if (resend)
      {
         if (mTarget.transport)

Does anyone have any ideas about the cause of this?
