ipython qtconsole gives error is python2 is included in PYTONPATH

I am no sure if it is an error, but if we have:

echo $PYTHONPATH 
/usr/lib/python2.7/site-packages:/usr/lib/python3.3/site-packages

Then this will happen:

ipython qtconsole

As you see python2.7 is executed in python3 program.

Is it a bug, shall I fill a bug report?
