Comment 26 for bug 181473

> Crash on Ubuntu 11.04, Inkscape revision 11529, when
> dropping a sublayer under the containing layer.

Reproduced on OS X 10.7.4 (gtk2 2.24.10), but only if a sub-layer is dragged out of its containing layer and dropped at the bottom of the (top-level) layer list. No crash if the sub-layer is dropped elsewhere as top-lavel layer (assuming several top-level layers with sub-layers).
