I'm not sure if I can reproduce this.
If I set 'backend: GTK' in ~/.matplotlib/matplotlibrc
and launch "ipython qtconsole --pylab"
then matplotlib.pyplot.get_backend() reports "GTKAgg".
In this configuration I am getting the dead kernel dialog,
but not in a predictable way (e.g., sometimes it is enough
to import matplotlib.pyplot and try to call get_backend,
sometimes I need to do a bit of real work before seeing
The problem doesn't appear to repeat with my default (TkAgg backend)
I've been using the TkAgg backend with the qtconsole for my day-to-day
work for the last few weeks without seeing the dead kernel dialog or
noticing slow response.
Ubuntu 10.04 32bit
ipython baf566fa94e3be8c383fab4a4c628c2c08e5797e (just pulled from master)
matplotlib from apt (0.99.1.2-3ubuntu1)
