1 - pngdec should negotiate with ximagesink (see first output bellow)

2 - if I dont put additional thread (fakesrc ! fakesink)
  it just get EOS without any message or screen (see second output bellow)

3 - if I put the additional thread (fakesrc ! fakesink) I get the message
"not-negotiated" which is unexpected

4 - filesrc ! only_chain_func_element ! pngdec ! ximagesink (I think I got
GST_FLOW_RESEND for gst_pad_push) and it just finish without do nothing (no
msg, no screen)

5- filesrc ! only_chain_func_element ! pngdec ! ximagesink fakesrc ! fakesink
(I think I got GST_FLOW_RESEND for gst_pad_push) and it just finish without do
nothing (no msg, no screen)

6- by just putting ffmpegcolorspace between pngdec and ximagesink everything
works fine. BUT ffmpegcolorspace shouldn't not be need in this case.
