QNSListener is implemented in both

[AwayFromKeyboard]

Hi, everyone!
I'm trying to have some XML and network programming experience, so i decided to compile WeatherTrayIcon project (M. Summerfield). All compiled well.
But after trying to run it, got this warning:

@objc[36326]: Class QNSListener is implemented in both /Users/artem/Qt/5.1.1/clang_64/plugins/bearer/libqcorewlanbearer.dylib and /Users/artem/Qt/5.1.1/clang_64/plugins/bearer/libqcorewlanbearer_debug.dylib. One of the two will be used. Which one is undefined.@

and it seems like program doesn't work properly.
After some surfing i found this bug report:
https://bugreports.qt-project.org/browse/QTBUG-27908

looks like it is still got no issue. Any ideas, why does it appears and how i can fix it?
P.S.: using OS X 10.9 and Qt 5.1.1 with 2.8.1 Qt Creator
