[Inkscape-user] Perspective Path Effect on groups

I'm on the PPA of a (very) shaky Inkscape 0.92 devel build. (Ubuntu 16.04)

Can anyone describe how to get perspective on a group?

I watched the youtube (linked from the release notes) but it does not match what I see on my end.

Steps: 1. Draw a few circles. Group them. Select the group. 2. Open Path Effects window. Add "Perspective/Envelope". 3. Switch to the node tool (manually). 4. Drag the corners around.

It: 1. Only affects one thing in the group. 2. or crashes Inkscape. 3. or does nothing. The group remains the same.

Mystified, /d
