------- Comment #6 from Tim-Philipp Müller  2007-09-12 18:00 UTC -------
This looks like a problem with the JESS visualisation.  I can reproduce this
with GStreamer CVS and libvisual0.4 (gutsy packages) on x86-64 like this:


 gst-plugins-base/tests/check$ LIBVISUAL_UNIT_TEST_FACTORY=libvisual_jess make
elements/libvisual.gdb

Program received signal SIGSEGV, Segmentation fault.
