[Qgis-user] problems with polygonize with qgis2.2

[William Kyngesburye]

Does the import work from python in a Terminal? (make sure it's the system python, /usr/bin/python)

> Also, I wonder if the extra copy of the Processing plugin is the problem (your error is coming out of your .qgis2 installed (updated) plugins).  Possibly you updated the processing plugin in QGIS 2.0, but now it's older than the copy in 2.2.  Try deleting the copy in ~/.qgis2.
