This happens when using qtconsole to display plot

This was already fixed, see issue #6878. It seems it'll be released in IPython 2.4.

got it, thanks

sorry to ask this here but how often do you update pip? the version there is still 2.3.1 and showing this bug.

I thought IPython guys were going to release 2.4 quickly but it seems
they are focused now on getting 3.0 out of the door (which this fix too).

So maybe 2.4 is not going to be released after all :-)

2.4 will still happen, probably around the same time as 3.0.
