gst-compprep-0.8 is triggering that too.

Created attachment 26362 [details] [review]
checks and corrects ladspa parameter bounds, before using them as g_param_specs

when initialising a g_param_spec with wrong values, the user will get a glib
critical message, this prevents it from happening [in this case ;-)].
I notified the original ladspa plugin author to fix it as well.
