Subject: using yscrollcommand in tkcanvas crashes R (PR#13231)

I don't know if this is the case here or not, but putting in scrollbars and scrolling can be a bit tricky. It usually works best to create the canvas without a scroll command, then create the scrollbar(s), then use tkconfig to go back and add the scroll command to the canvas after the scrollbar has been created and placed.
Hope this helps,
