Thanks for the logs!

I had a look at the test_buffer_probe_n_times test failure yesterday. The
problem is that fakesink does not push the latency event it receives via the
send_event vfunc upstream, so the event probe only ever sees the newsegment and
eos events, but no latency event.

So the sequence should be:
A gstevent.c:1062:gst_event_new_latency: creating latency event
B gstevent.c:267:gst_event_new: creating new event 0x809d0a0 latency 289
C gstelement.c:1384:gst_element_send_event: send latency event on element
D gstbin.c:2462:gst_bin_send_event:<pipeline0> Sending latency event to sink
E gstelement.c:1384:gst_element_send_event: send latency event on element
F gstbasesink.c:3586:gst_base_sink_send_event:<fakesink0> latency set to
G gstpad.c:4521:gst_pad_push_event:<fakesink0:sink> event: latency
H check gst/gstutils.c:63:event_probe:<fakesink0:sink> event probe 2 [latency]
I gstpad.c:4573:gst_pad_push_event:<fakesink0:sink> sending event latency to
peerpad <fakesrc0:src>
J gstpad.c:4698:gst_pad_send_event:<fakesrc0:src> have event type latency
K gstevent.c:223:gst_event_finalize: freeing event 0x809d0a0 type latency

But steps G-J are missing in your case.

How or why that would happen, I don't know. My best guess would be that, for
some reason, ../../plugins/elements/.libs/libgstcoreelements.so does not
link/use the libgstbase-0.10.so in the source tree, but an older installed
version from elsewhere. I can't reproduce the problem myself though, it seems
to use the internal lib just fine for me (libtool 2.2.4, automake 1.10.1,
autoconf 2.61).

Maybe you could add a g_print ("forward latency event %d\n", forward); in
libs/gst/base/gstbasesink.c line 3592 (in the GST_EVENT_LATENCY case in
gst_base_sink_send_event), to see whether (a) the locally built
libgstbase-0.10.so is used, and (b) whether it tries to forwarded the event or
