Crash when closing a QML app with debugger session

Using Qt Creator and its QML Inspector to open a debugger session for a QML file, you get the following assert when closing the viewer:
ASSERT: "runningLeafAnimations >= 0" in file /home/lasse/dev/qt/qt-qml/src/corelib/animation/qabstractanimation.cpp, line 324

In this case, I was debugging examples/dial/dial-example.qml. If I run the example without debugging, no crashes occur - hence the assumption that it's the debugger.
