Unfortunately yes, I have seen a problem like that in the past. It was very frustrating and tedious to isolate the root cause, because of its intermittent nature and the requirement to unload the plugin to cause the crash. Eventually I determined that it was related to some dynamic resizing of scrollbars I was doing. Although I was never able to figure out the exact nature of the problem, I worked around it.
I think Garan has mentioned other known things that can cause this, but I don't know what they are.
