     def modify(self, meta, data, comment=u'', contenttype_guessed=None, **update_meta):
         meta = dict(meta)  # we may get a read-only dict-like, copy it
+        # get rid of None values
+        update_meta = {key:value for key, value in update_meta.items() if value is not None}
         meta.update(update_meta)

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
