Looks like a memory corruption before that...

could you run

G_SLICE=always-malloc GST_REGISTRY_FORK=no valgrind --leak-check=full
--track-origins=yes gst-inspect-0.10 

And attach the complete output here?

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

Again, thanks for your help, even Gnome-session its broken :(

Looks like valgrind is broken on your system :( That doesn't really
help...

What's the content of your /usr/lib/lv2 , ~/.lv2 and /usr/local/lib/lv2
directories?

Could you attach the file "log" that is generated by:

GST_DEBUG=lv2:5 GST_DEBUG_NO_COLOR=1 gst-inspect-0.10 lv2 &> log

> Again, thanks for your help, even Gnome-session its broken :(

As a short workaround you can
remove /usr/lib/gstreamer-0.10/libgstlv2.so

Subject: Same problem, but it disappeared after installing debug package..

Date: Fri, 02 Oct 2009 22:24:18 +0100

Hello,

I had the same problem here -- segmentation fault while
loading  /usr/lib/gstreamer-0.10/libgstlv2.so .
(in Debian/testing, amd64 as well).

I did generate the valgrind report, as suggested. Lot's of '???'
in there, so  I thought I'ld improve the report by installing
libgstreamer0.10-0-dbg. But that made the segmentation fault disappear!!!

And even stranger, after purging libgstreamer0.10-0-dbg, the
segmentation fault does not reappear!!

Unfortunately I overwrote the valgrind output for the crashing case.
In the non-crashing case it reports various leaks as well, but that's
probably just intended / sloppy programming; I've included the start/end
of the valgrind output below (let me know if you want to see the middle bit).
I did have the impression that with the segfault valgrind did take
far longer, and reported far bigger numbers.

Could this be a race in gobject? After all it crashes in
gst_signal_processor_pad_get_type
and not in gst_signal_processor_get_type.

What I wonder if it would help to do this? Other plugins like e.g. jack,
baseaudiosink, .. do that too.

If you use G_DEFINE_TYPE() or have g_once_init_enter/leave in the
_get_type() functions this shouldn't be necessary.

Also most other places where this could happen are doing exactly what
you said already :)

I think you should use G_DEFINE_TYPE() if possible in
gstsignalprocessor.



BUT: this can't be the problem here because all code was called from the
registry and that happens from a single thread, in a wonderful
serialized way :(
