Question about subclassing Gtk2::TextBuffer

[Jaap Karssenberg <j g karssenberg student utwente nl>]

Greetings,

I overloaded Gtk2::TextBuffer to add some more "high level" methods for 
dealing with the parse trees I use in zim, as well as enforcing edit 
modes and adding an undo-stack. I just followed Glib::Object::Subclass 
using INIT_INSTANCE etc..

Now I get this warning every time a new buffer object is created:

	Gtk-CRITICAL **: set_table: assertion `buffer->tag_table == NULL' 
failed at lib/Zim/Components/PageView.pm line 447.

( The line number reported in the error is the line where I call the 
constructor for my overloading class )

It doesn't seem to affect usage of the class but it can be rather 
annoying when running my program from the commandline.

Any suggestions on turning off or avoiding this waring ?
