No verbose mode in gst-launch-1.0?

Hi,

Sometimes it is nice to see what is going on in the pipeline. I installed
GStreamer 1.2.0 for OS X and I noticed that verbose mode does not work
correctly.

Test pipeline:
gst-launch-1.0 -v fakesrc num-buffers=3 ! fakesink

And log:
"Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Got EOS from element "pipeline0".
Execution ended after 0:00:00.000180000
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ..."

But when I use gst-launch-0.10 (included in GStreamer 0.10.36):
gst-launch-0.10 -v fakesrc num-buffers=3 ! fakesink

My log is:
"Setting pipeline to PAUSED ...

Am I missing something or maybe today is not my day to struggle with
GStreamer...
Sorry for so many questions but it is hard to find complete documentation
containing information about the newest GStreamer version.

Thanks in advance.
