Description
To reproduce:
1. Open a session containing Creator project
2. Start Analyze | CMake Profiler. After about 10 seconds: crash.
Once, I got the following assert prior to the crash:
ASSERT failure in QCoreApplication::sendEvent: "Cannot send events to objects owned by a different thread. Current thread 0x0x556731bf76c0. Receiver '' (of type 'CtfVisualizer::Internal::CtfVisualizerTool') was created in thread 0x0x55672ef694f0", file /home/jarek/dev/qt-65/qtbase/src/corelib/kernel/qcoreapplication.cpp, line 535
The crash happen in non-main thread.
