Similar bug is
http://bugzilla.gnome.org/show_bug.cgi?id=423057
which relates to
http://bugzilla.gnome.org/show_bug.cgi?id=329454
with a long discussion of threading issues. gstreamer python backend
indeed had problems with glib threading system initialization as well as
can conflict with at-spi threading. Anyhow that will require additional
debugging of at-spi module. At least you have to find what particular
corba exception is returned. Probably ORBIT2_DEBUG can help here, but
you have to recompile ORBit2.
Are you sure threads are initialized properly in your app, is there
source code to look?
