[Gimp-developer] Discrepancies in the Python API between 2.6 and 2.8

[Ofnuts <ofnuts laposte net>]

Warning: first off, due to a rather ancient Ubuntu version, I'm not 
really testing things with 2.8 but with a home-built 2.7.2 (going beyond 
that causes a dependencies avalanche)...

This said, a script of mine out in the Internet wilderness is reported 
as failing on 2.8. When I run it on my 2.7.2, I find that;

    layer=image.layers[0]
    pdb.gimp_drawable_is_text_layer(layer)

elicits a "wrong parameter type" while

    pdb.gimp_drawable_is_text_layer(layer.ID)

works (gimp_item_is_text_layer() has the same problem). In 2.6 all the 
PDB procedures take objects and not integer IDs, so is this a voluntary 
change?

Next, if the layer is indeed  a text layer;

   pdb.gimp_text_layer_get_text(layer)

returns None despite the layer having text.

Are these known problems? Are they already fixed in 2.8? Or should I 
file a report on Bugzilla?
