xml serialisation has some limmitations and is not widley used. In the
above case it might fail to handle the dynamic pads. You could use
G_DEBUG=fatal_warnings gdb --args gst-xmllaunch -vvv saved_pipe.xml
and break on the error. Get the backtrace, figure a fix, report
problem+backtrace+patch to bugzilla.
