Ok. This is an ad-hoc solution that will definitely fail somewhere  
down the road.

In gettext_compile.erl find the following function:

pt([H|T], Opts, Func) when is_tuple(H) ->
    ?debug( "--- 3 --- ~p~n",[H]),
    [while(size(H), H, Opts, Func) | pt(T, Opts, Func)];

change it to:

pt([H|T], Opts, Func) when is_tuple(H) ->
    ?debug( "--- 3 --- ~p~n",[H]),
	case H of
		{call, _, _, _} ->
			[pt(H, Opts, Func) | pt(T, Opts, Func)];
		_ ->
			[while(size(H), H, Opts, Func) | pt(T, Opts, Func)]
	end;

This way pt/3 will not miss the function call to key2str/2. Hopefully...
