[Bug 1249571] Re: Segmentation fault on Ubuntu 13.10 when using guiqwt

[Ningfei Li]

Hi Scott,

Thanks again for your quick reply! Here I can give a short test script to reproduce this problem (as in attachment).
It's basically a test case provided in guiqwt.tests (histogram.py). 
During debugging, it will stucks at line 12: win = CurveDialog(edit=False, toolbar=True, wintitle="Histogram test")
Then you trace into it to plot.py, curve.py and then baseplot.py. Finally you will be here in baseplot.py: self.emit(SIG_PLOT_LABELS_CHANGED, self) in function: def update_axis_style(self, axis_id)

Package: python-qt4 (4.10.3-1ubuntu1)
Package: python-sip (4.15.2-1ubuntu1)

reverting to python-qt4 (4.10-0ubuntu3) ) and python-sip
(4.14.5-0ubuntu1) then everything works fine.
