Your symptoms are very, very strange.  Please try to see if the you get 
similar problems by running a trivial script that causes an exception, like 
1/0.  I want to make sure that we isolate this to ipython, and not something 
you're running.

That missing (Pdb) prompt in your system is _really_ strange, and it tells me 
that somewhere, something is badly broken.  But I have no clue what.

There are also hints of COM objects in your system:

<unknown>> in Item(self, Index)

I wonder if those are the ones causing the Ctrl-C problems.  It may be that 
one of those is loading a SIGINT handler, thus messing up python's own.

Please try to reproduce these symptoms with as small a script as you can, and 
hopefully something that doesn't require any of your own data or personal 
libraries.  Only that way can we isolate it, and perhaps either I or another 
user can think of a solution.

If you can reproduce it, please post exactly both the script used and your 
screen grabs with the results.
