Description Julien Isorce 2009-06-08 10:33:58 UTC 
****steps:

compile (gcc -Wall $(pkg-config --cflags --libs gstreamer-0.10) main.c -o main)

and run the attached example (24 code lines).

****result:

GStreamer-CRITICAL **: gst_structure_to_string: assertion `structure != NULL' failed

GLib-CRITICAL **: g_strescape: assertion `source != NULL' failed


****other infos:
No failure if I remove the "EXTRA_HEADERS" property of the souphttpsrc.
So maybe something is wrong with this property or handled in a bad way.

Comment 2 Tim-Philipp Müller 2009-06-15 20:18:45 UTC 
This looks like a bug in the xml serialisation code (not allowing NULL for GstStructures or so), so moving to core.

FWIW, the GstXML API is unloved if not unmaintained and known to be buggy and hence not really recommended for use.
Comment 3 Tim-Philipp Müller 2009-06-16 07:56:18 UTC 
This should hopefully fix it:

    gstxml: fix (de)serialisation of properties of type GstStructure
    
    souphttpsrc has a property of type GstStructure, which causes an
    assertion when serialising it to xml. Fixes #585137.


Still, please don't use this API for anything serious.
