Try to figure out what "ntb->GetSelection()" returns - since it is an "int" and "ntb->GetPageText()" takes an "size_t" there might be some signing issue. Also; You might want to use "event.GetSelection()" or "event.GetOldSelection()" in the event handler instead.
I have a bad habbit of not testing the code I post :D

I usually observe wxArgNormalizerWchar errors when using wxString::Format or similar.

If this is the case you might be using a %d for a size_t type instead of %lu.

Some people, when confronted with a GUI problem, think "I know, I'll use Eclipse RCP". Now they have two problems.
