QML profiler fails on specific example(s) on QNX

Qt for QNX 5.9.1 RC offline package installed (qt-enterprise-linux-x64-qnx-5.9.1_680) including Creator 4.3.1.

Creating new QtQuick application or opening Calculator example and launching QML profiler works ok. Selecting Clocks example and launching QML profiler produces error:
