PyQt4-4.8.6-1.fc16.x86_64
But interestingly, I'm not actually using the display in this script. I'm using
pdfpages.
The basic outline is:
At the start:
from matplotlib.backends.backend_pdf import PdfPages
self.pdf = PdfPages(file_name)
Then at the start of each page I do:
self.prop = mpl.font_manager.FontProperties(size='xx-small')
self.fig = fig = plt.figure()
self.ax = fig.add_subplot(111)
fig.subplots_adjust(bottom=0.2)
self.colors = itertools.cycle(['r','g','b','c','y','m','k'])
self.markers = itertools.cycle(['o','s','v'])
Then at the start of each plot on a page I do:
self.ax.semilogy (esno, [e for e in per], c=self.colors.next(),
marker=self.markers.next(), label='iter=%s'%n_iter)
Finally, to finish each page:
plt.title (...)
plt.grid(which='major', linestyle='solid')
plt.grid(which='minor', linestyle='dashed')
plt.legend(prop=self.prop, loc='best')
self.ax.set_xlabel ('\{E\_s\}/N\_0')
self.ax.set_ylabel ('per')
plt.figtext (0, 0, res['carriers'].values, horizontalalignment='left',
verticalalignment='bottom', size=5)
self.pdf.savefig (self.fig)
plt.close()
Then when all pages are done:
self.pdf.close()
It looks like I'm getting one of these error messages for each page.

Can you provide more detail about how to reproduce this?
I can deduce you're using the Qt4Agg backend -- but running
simple_plot.py, zooming around, and then closing the window does not
seem to reproduce the error here.What version of Qt/PyQt/PySide are you running. What platform?
