Comment 10 for bug 249035

Odd - I'm using linux, and it crashes every time. And you are correct - the test extension is setting the first layer's style to "display:none".

If I add a second line to the extension that then sets the style to "display:inline", then Undo does not crash.

I'm python 2.6 and lxml 2.1.5 here on linux.

OK - that extension and then an undo on win XP also crashes. Inkscape 0.46.

Thanks for the info on the namespace change.
