[solved] cocos.text can traceback with AttributeError: 'RunIterator' object has no attribute 'length'

[ccanepa]

solved a bit, but you need to upgrade to latest pyglet master (and now Label instead of HTMLLabel will be broken; waiting for a more complete pyglet fix correcting both cases)

runing test_htmllabel_opacity.py got traceback

Reproduced with a pure pyglet script, opened an issue at pyglet github issues,
pyglet/pyglet#40

[ccanepa]

solved: pyglet fixed the issue. You will need to update from pyglet master if you experience this problem.

Keeping open until next pyglet release.

The pyglet fix for the initial issue broke changing color for Label

Opened pyglet/pyglet#45

The cocos related crashes are:

test_label_changing.py
test_label_opacity.py

The traceback from thje first (the other ends the same)

Deleting the [Solved], the two cases, Label and HTMLLabel, will need a shared fix from pyglet.
