> I think this bug (#271723) is exactly same as bug #463602.
No, I don't think so - at least is has not been confirmed as such. Please read the original bug report here (bug #271723) and earlier comments which explicitly state «Any imported pattern I try to drag, scale, or rotate causes a segmentation fault (though I'm always using very large patterns, over 1600x1200 pixels). The built-in patterns do not.» and another «Built-in patterns are ok»
The example you attached however uses the built-in 'Stripes' pattern and looks like the issue reported in bug #463602 (which is marked as fixed in bzr trunk).
