TaskList doesn't work with Zim 0.67

[Guilhem]

Hello ,

I use the zim portable version 0.67 on window.
I install the TaskList plugin in ZimDesktopWikiPortable\App\Data\zim\plugins .
I can activate the plugin and change configuration.
But after validate there is no button fort task list.

When i launch zim in debug mode , i have the following error :
ERROR: Exception in plugin: tasklist
Traceback (most recent call last):
  File "zim\plugins\__init__.pyo", line 293, in _foreach
  File "zim\plugins\__init__.pyo", line 305, in <lambda>
  File "s:\Users\gsuarez\Documents\SOFT\ZimDesktopWikiPortable\App\Data\zim\plugins\tasklist.py", line 263, in extend
TypeError: get_extension() got an unexpected keyword argument 'index'

Thanks a lot for your help.
