QML viewer fails to close the process on exit when running declarative Flickr demo on Symbian^3

The memspy shows that the thread is left hanging when I run a more complex qml example like declarative flicker demo either in qmlviewer or as a standalone application even after quitting and restarting the memspy. The process closes fine when I run simpler qml applications.

Memspy shows
qmlviewer 20021317, 1 thr, [B]
qmlviewer 20021317, 1 thr, [F]

Also, trying to open qml.log file with FileBrowser after exiting qmlviewer that opened flickr demo results in "The file is in use, cannot open" warning, suggesting QML Viewer's handle to the file is still left open.
