Crash in latest LE/OSMC builds

Pi3b.
Since LE #328 and OSMC 17.8-048 Kodi crashes under the following circumstances:
Start playing any video [mine are on a Windows box, shared via SMB].
Bring up the Video OSD by hitting ‘m’ on keyboard.
Let it continue for a few seconds.
Exit OSD by hitting ‘m’ again’.

Crash – Kodi crash, not reboot.

Any one else observed this?

Reverting to LE #327 and OSMC 17.8-047 fixes issue.

I will find a crashlog from LE once I’ve reproduced with stock Estuary [which I don’t normally use].
Will also try a local rather than network file.
No reason to suspect skin as it happens with both Estuary V1 and Xonfluence 3.3.17
