I think that commit b46615c55ad2c8fe6de54412055a0713da3d610a could be the culprit.

Shouldn't every reply start with StartMessage() ? In the app server, file ServerApp.cpp, lines starting from 663:

case AS_SET_DECORATOR:
{
	// Attached Data:
	// path to decorator add-on

	BString path;
	link.ReadString(path);

	status_t error = gDecorManager.SetDecorator(path, fDesktop);

	fLink.Attach<status_t>(error);
	fLink.Flush();

	if (error == B_OK)
		fDesktop->BroadcastToAllApps(AS_UPDATE_DECORATOR);
	break;

I think it's missing the fLink.StartMessage(error)
