--- Comment #2 from Romain Geissler <romain.geissler at amadeus dot com> --- Yes this is what I did, I reverted back to ISL 0.21 which for me has been working for the past months (don't know if it's a recommanded version though). Shall we keep this bug open to track the upcoming support of in-tree 0.22 or shall it be closed ?
