安装qt5后编译运行后有关Qt at-spi的警告

                     系统ubuntu12.04安装qt5，编译完成后，在运行软件时，老是

                    Qt at-spi: error getting the accessibility dbus address:  "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

                   但愿有谁可以解决下，我在外国找解决办法，说是ubuntu的一个bug，只要卸载qt-at-spi就行，但是我照作了仍是没用。在外国找资料，那网速不敢恭维，没的查，但愿你们一块儿解决。
