Your basic problem is that "run -d" is broken in some version combinations of
IPython/Python. See here for a workaround (pydb):
The usual way to use breakpoints in IPython is either e.g. "run -d -b 3
test.py" (setting a breakpoint on line 3) or "run -d test.py", stepping in
(debugger command "s") and setting new breakpoints with debugger command "b".
For post-mortem debugging (your "1/0" example) I don't use breakpoints, because
I don't think you can resume normal program flow after an uncaught exception.
Instead normally just use the debugger to inspect variables or evaluate some
expressions, then run my program again with a breakpoint just before the
Hope this helps,
