[arch-general] Is qt 4.4.2-1 broken?

Hi, all After upgrading to qt 4.4.2-1, I found that some qt4 program became broken, such as VirtualBox, and Qterm. All of these programs get a error like this: process 4272: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details. Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection. D-Bus not built with -rdynamic so unable to print a backtrace Aborted Is it really a bug of application, or just a bug of qt, or just a bug for this package?
