[FIXED] ipython 0.11 exception visible only after exit of pdb

Issue

both in ipython 0.10 and 0.11 I set the automatic launch of pdb on exceptions.

In ipython 0.10 it works fine:

In [1]: 1/0.
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)

/home/zonca/<ipython console> in <module>()

ZeroDivisionError: float division by zero
> <ipython console>(1)<module>()

ipdb>

instead, in ipython 0.11, the exception is NOT visible:

In [1]: 1/0.
> <ipython-input-1-7e0bf5b37da6>(1)<module>()
 -1 1/0.

ipdb> 

I see it just when I exit the debugger!

In [1]: 1/0.
> <ipython-input-1-7e0bf5b37da6>(1)<module>()
     -1 1/0.

ipdb    >

----> 1 1/0.

Anybody else has this issue? I'm on Ubuntu, with python 2.7.2, ipython installed with pip.

Solution

It's a known issue with IPython 0.11. It will be fixed in 0.12 (which will hopefully be out before Christmas).
