Which is available in point context menu for a smooth tangent point after point is moved.
Can you post a screenshot of the original path with the selection you are trying this?
sure.
this is ‘A’ from Lato Regular.otf: command is not available if I just r-click this point, but after I move it, it appears in menu, then crashes.
this is relevant piece of the crash report:

interesting: after one more crash on this subject I cannot run G3 anymore, crashes on startup 
system reboot didn’t help, is there some way to run G3 in “safe” mode?
looks that deleting G3 data from ~/Library/Autosave Information helped.
but I also deleted all other references to G3 data from user/library, that was just the final one after which it now starts again.
I can send A_.glyph file (which I saved just before the crash), but forum engine doesn’t trust me with this. Let me know where I can send it.
Try zipping the file or send it to support at this domain.
done.
