Messages of type=headline are ignored if they have a data form child
<message to='MY_JID' type='headline'>
<body>Reply with "yes" to allow it</body>
<x xmlns='jabber:x:data' type='form'>
<title>Joogle Search</title>
<instructions>Fill out this form to search for information!</instructions>
<field type='text-single'
var='search_request'>
<required/>
</field>
</x>
</message>
Does not even display the body to me on Gajim 0.16.5. Using type=chat shows only the body and ignores the data form. type=normal shows the data form as expected
