I made this report after the crash had occurred four times. I tested on different files, some on the server, others running locally. However, since adding this report I saw another application crash. I rebooted the machine and this issue has disappeared.
Thank you for your posts.
If this crash reappears, please also post the crashed thread. For example, in your initial posting, you cut off the crash report at the crashed thread (Thread 0). If you had included Thread 0, this may have provided a clue to why the crash occurred.
