I'm tried to simulate example from quick start, but faced with error «checker error, no actions defined: nothing to do»

# Qucs 0.0.15 ~/qucs/1.sch

AND:Y1 Out _net0 _net1 V="1 V" t="0" TR="10"
DigiSource:S2 _net0 init="low" times="[2ns; 2ns]" V="1 V"

You need to add a simulation. Go to Components > Simulations > Digital simulation, and drag and drop it to the schematic.

This is not a bug. You need to place a simulation box on the schematic to tell the simulator what to do. In your case you can add digital simulation.
