      On some Windows 7 hosts QtWebEngine demobrowser crashes on quit. I was able to reproduce this issue by closing demobrowser right after first webpage elements are becoming visible. If I wait for a page to load further, bug is rarely triggered.

      Application that I develop crashes with the same backtrace much more frequently than demobrowser in the same environment.

      I've also tried to crash quicknanobrowser, but was unsuccessful.

      Backtrace and qtdiag output is in the attachment.
