I obtained more information about the problem.  I execute
gst-inspect... -gst-debug=*:5
and I obtain the following error:
attempt to load plugin "...libgstapp..."
Could not find plugin entry point in ...libgstapp...

so the plugin is found, but there is an error when loading it.

I looked in the code and found that the error is because a symbol is not 
found:
   ret = g_module_symbol (module, "gst_plugin_desc", &ptr);
   if (!ret) {
     GST_DEBUG ("Could not find plugin entry point in \"%s\"", filename);

However, grep shows:
snoopy:~/softs/ekiga$ grep -r gst_plugin_desc gst-plugins-base-1.2.2/
Binary file gst-plugins-base-1.2.2/gst/app/.libs/libgstapp.dll matches
Binary file gst-plugins-base-1.2.2/gst/app/.libs/libgstapp_la-gstapp.o 
matches
gst-plugins-base-1.2.2/gst/app/.libs/libgstapp.dll.def:gst_plugin_desc DATA
gst-plugins-base-1.2.2/gst/app/.libs/libgstapp.exp:gst_plugin_desc DATA
[...]

so I am lost on what could be wrong here.

Can someone help here?
