OK so briefly, the problem was with the get_state function in togglePlayback.
With some clips, when you seek at a certain position, only part of the bins see
their state set to PAUSED. So when you do a get_state on the pipeline, it never
returns.
What puzzles me is the logs from GST_DEBUG.
When doing an "incomplete" seek, you will get this :

0:00:09.687979007 20400 0x7fbb30002a00 INFO              GST_STATES
gstbin.c:2910:bin_handle_async_done:<videosink> committing state from PAUSED to
PAUSED, old pending PAUSED
0:00:09.688140586 20400 0x7fbb30002a00 INFO              GST_STATES
gstbin.c:2930:bin_handle_async_done:<videosink> completed state change, pending
VOID
0:00:09.688203016 20400 0x7fbb30002a00 INFO              GST_STATES
gstbin.c:2910:bin_handle_async_done:<vbin> committing state from PAUSED to
PAUSED, old pending PAUSED
0:00:09.688376366 20400 0x7fbb30002a00 INFO              GST_STATES
gstbin.c:2930:bin_handle_async_done:<vbin> completed state change, pending VOID

When the seek is succesful, two more elements are added to this log :
gestimelinepipeline1 and internal-sinks.

I pushed a branch called deadlocks on my github that at least prevents the
deadlocks.
