I assume Gstsubtitlefilter is your new element? This sounds like a
problem in either the struct definitions or the GObject type
registration. Check if you have the correct first element in your
instance and class struct, and use the same type as the parent type
when registering your type.

My best guess here would be that you use GstBin as your parent type,
but the structs only contain a GstElement/GstElementClass in the
beginning.
