 (In [c2b098e0aaf7e6fffec72b3130cb4c851c7a64c1]):[[BR]]
 *** Plucked rev fade006b (malu at pidgin.im):
 Only pre-create a PurpleConversation (if there was none yet) if an
 incoming
 message contains custom smileys.
 Partly fixes the \"popup a conversation window when set to hide\" bug.
 Until I found a better way to fix entirely...
 Refs #7380

 *** Plucked rev 120a0724 (darkrain42 at pidgin.im):
 Only look for and add custom smileys to incoming messages that are going
 to
 end up being displayed in a conversation window (i.e. not headline
 messages).
 Closes #7516.
