Hello Romain-guy,
I would be happy to if I knew how to properly answer your request.
I removed the breakpoint on the getitematpos call and let it rip.
Then when it crashed, I went to debugger window and did a copy of the
stack trace and posted it below:

If i comment out the getitematposition line it will run ok.
