QtApplication in Netbeans: "Not connected to D-Bus server"

Question

I have created simple QtGui Application in QtCreator. it works. then I have created QtApplication in Netbeans and added files generated in Creator (mainwindow.h,cpp,ui_mainwindow.h) to new Netbeans project. it compiles, links, builds. when I try to run executable, the window appears but there is also this message:

root@comp:~/NetBeansProjects/QtApplication_3/dist/Debug/GNU-Linux-x86# ./QtApplication_3 Qt at-spi: error getting the accessibility dbus address: "Not connected to D-Bus server" Accessibility DBus not found. Falling back to session bus. Could not connect to DBus. Could not connect to dbus.

(process:10309): GConf-WARNING **: Client failed to connect to the D-BUS daemon: 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.

** (QtApplication_3:10309): WARNING **: Unable to create Ubuntu Menu Proxy: The connection is closed root@ubuntuamd:~/NetBeansProjects/QtApplication_3/dist/Debug/GNU-Linux-x86#

how is this related to network connection? this is just window. is my approach OK to copy the code generated in Creator? maybe then I have to do something additionally?
