pdb uses os.path.abspath and os.path.normcase to normalize filenames so 
they can be safely compared (see the canonic method in

I suggest you do the same in your editor; e.g:

     pdb_filename = ...

     for buffer in editor_buffers:
         filename = os.path.normcase(os.path.abspath(buffer.filename))
         if pdb == filename:
             ... found it ...
