An instance of FrontendAppeared is created in frontend_manager module
and sent to the actor defined in control_window module which has:
import frontend_manager: FrontendAppeared
It seems the symbol FrontendAppeared in control_window is matching the
FrontendAppeared type of the message sent, and yet the assertion fails.
it may be something with struct copying. variant wants to copy a struct
into itself, and somehow failed. either there is no room, or something
prevented it to do that. it is hard to say more without full source code.
