unity-2d-places crashed with SIGSEGV in QTJSC::Structure::materializePropertyMap()

[Martin Pitt]

Binary package hint: unity-2d

This crash happens when you boot current oneiric-alpha-1 (which defaults to unity-2d due to a bug which just got fixed), and click on the bfb (Ubuntu logo in the corner). It happens on the i386 and amd64 images, in kvm and on real hardware, so it doesn't seem hw specific at all.

This looks like a crash in either GTK, Cairo or librsvg.
Can you try to load some SVG icons from /usr/share with /usr/bin/rsvg-view?

[Martin Pitt (pitti)]

I tried rsvg-view on several icons of different size in /usr/share/icons/Humanity/ in the live session, and they all work fine. They also work with eog.

This seems fixed for me now, just checked today's daily in KVM.
