assistant startup takes several minutes with -enableremotecontrol

On my computer, I'm interfacing my IDE with assistant using the -enableremotecontrol argument.

It works fine, excepts that it's very slow to start. I've narrowed the problem in the MainWindow::checkInitState function.

in remote control mode, it's called several times. The function HelpEngineWrapper::instance().initialDocSetupDone(); is called several times too, connecting signals several times.

If I modify the start of the function this way :

void MainWindow::checkInitState()
{
    TRACE_OBJ
    if (!m_cmdLine->enableRemoteControl()) {
	    HelpEngineWrapper::instance().initialDocSetupDone();
	    return;
    }

    HelpEngineWrapper &helpEngine = HelpEngineWrapper::instance();
    if (helpEngine.contentModel()->isCreatingContents()
        || helpEngine.indexModel()->isCreatingIndex()) {
        if (!m_connectedInitSignals) {
	    HelpEngineWrapper::instance().initialDocSetupDone();

startup becomes normal again. I'm not sure this is the proper fix though.
