Simply open/close a document, if you track down the allocated GlobalAcceleratorConfiguration objects, you will find all are not freed finally.

The reference which cause this object can not be freed is at, 

void GlobalAcceleratorConfiguration::impl_ts_fillCache()
{
    // get current office locale ... but dont cache it.
    // Otherwise we must be listener on the configuration layer
    // which seems to superflous for this small implementation .-)
	::comphelper::Locale aLocale = ::comphelper::Locale(m_sLocale);
    
    // May be there exists no accelerator config? Handle it gracefully :-)
    try
    {   
        m_sGlobalOrModules = CFG_ENTRY_GLOBAL;		
        XCUBasedAcceleratorConfiguration::reload();

		css::uno::Reference< css::util::XChangesNotifier > xBroadcaster(m_xCfg, css::uno::UNO_QUERY_THROW);
		xBroadcaster->addChangesListener(static_cast< css::util::XChangesListener* >(this));
    }
    catch(const css::uno::RuntimeException& exRun)
        { throw exRun; }
    catch(const css::uno::Exception&)
        {}
}

The listener will always keeps there without free.
