[Qgis-user] [Processing] error updating "Processing"

[Nicolas Cadieux]

Hi, 
Delete the .qgis2 folder in your user directory for each user. This is a hidden folder so you will need to unhide hidden folder and file in Windows. 
 This will remove all plugins you downloaded.  (You can back up the folder some where else if you what.  Then restart QGIS and reinstall your plugins. That should work.

	hi, i have some installation of qgis on my windows 8.
I installed via osgeo4w:
2.8.4-2 (LTR dev)
2.12.1-1 (Lyon)
2.13.0-21 (dev)
but there is a problem with the update processing.
In fact, if I upgrade it to 2.12.2 from 2.10.99, a directory called "processing" is created in C:\ Users\ ... \. qgis2\python\ plugins folder and this error comes out:
Couldn't load plugin 'processing' 
ImportError: cannot import name spatialite_utils

Python version: 2.7.4 (default, Apr  6 2013, 19:54:46) [MSC v.1500 32 bit (Intel)] 
QGIS version: 2.12.1-Lyon Lyon, 16760fd 
at this point, it no longer works neither processing nor any plugins associated (processing_workflow, and so on).
The only solution is to delete the directory called "processing", but that processing is outdated.
is this a bug?
thanks a lot
