Segmentation fault with g_object_set / strchr

问题:

This line get me a segmentation fault :

g_object_set(G_OBJECT(data.udpsrc), "port", 5000, "caps", caps, NULL);

where

• data.udpsrc = gst_element_factory_make("udpsrc", "source");
• caps = gst_caps_new_empty_simple("application/x-rtp");

Here's the output with gdb :

Program received signal SIGSEGV, Segmentation fault.

This is Bug 740191. You need to update Gstreamer to 1.4.5 version at least.
