Annoying "Qt VS Tools: QML debug: DISABLED" message

After the last update of Qt VS Tools 2.6.0, I'm receiving tons of the following messages in the output window:

Qt VS Tools: QML debug: Debugging project 'xxxxx'...
Qt VS Tools: QML debug: DISABLED: Non-Qt/MSBuild project
Qt VS Tools: QML debug: Debugging project 'xxxxx'...
Qt VS Tools: QML debug: DISABLED: Non-Qt/MSBuild project
Qt VS Tools: QML debug: Debugging project 'xxxxx'...
Qt VS Tools: QML debug: DISABLED: Non-Qt/MSBuild project
Qt VS Tools: QML debug: Debugging project 'xxxxx'...
Qt VS Tools: QML debug: DISABLED: Non-Qt/MSBuild project

It seems to be related to creating and destroying threads.

Is there any way how to get rid of these messages? It's very annoying.

PS: It seems that the issue can be temporary fixed with "Convert custom build steps to Qt//MSBuild", but as soon as I will run qmake I receive these messages again.

Thanks
