Hi Paul, I have also had his problem.
In most cases it was caused by some silly C++ mistake I made that was not caught. In one case I think it was the result of loading 2 plugins with duplicate name space (cut and paste error) which I think confused the debugger causing to to crash. Usually I had to resort to printf() debugging.
