as a workaround you need to go to
System -> Preference -> Screensaver
and disable
- Activate screensaver when computer idle
- Lock screen when screensaver is active

After this you do not encounter this issue anymore.
Bear in mind that you need to lock your workstation when you go to grab some donuts in the kitchen :-)
