Can't create BlackBerry Cascades application

Steps to reproduce the bug: Ctrl-N / Application / BlackBerry Cascades Application
Immediately after completing the wizard I get error message 'No plugin can open project type "text/x-c++hdr".' (see attachment)
After that, the "Projects" view on the left is showing the newly created project without *.cpp and *.h files, though the files are present on the computer. After adding the files to project and attempting to build I get "No rule to make target main.o".
My BB NDK is installed and working (I can create Cascades application successfully in Qt Creator 3.0.1 on the same computer).
