Depends on if the application itself or QT drops the dbus connection.
A backtrace would be interesting where the errors occur.
Kind regards,

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

Is it really a bug of application, or just a bug of qt, or just a bug
for this package?
