[ckan-dev] Problem removing datasets from a group through API

I'm not able to reproduce this behaviour using the latest development
version of CKAN (i.e. the current HEAD commit on the master branch at
github.com/okfn/ckan). Adding/removing datasets to/from groups with
APIv2 appears to work fine. What version of CKAN are you using?
