Rafael,
I'm testing the 0.48 version and I've noticed that when opening an svg file
created in version 0.47 in 0.48, some elements (arrows, in this specific case) that I had grouped with a main figure with other elements (rectangles, circles, etc..), now the arrows appears far away from the main figure in the canvas. Is that any known issue or problem ?
I suspect that this is due to nested <svg> elements; there were some fairly serious issue in 0.47 with those, where the positions would get messed up and go weird and occasional crashes would result. It happened that in some way the internal representation was incorrect (relative positions in the child <svg> elements) but Inkscape didn't quite realise that and rendered the positions correctly (mostly). This may have been fixed for 0.48, so that may be the reason why - it's rendering them *properly* now, and so it doesn't appear the same as in 0.47. If you can provide the actual files you're experiencing it with the issue could be analysed more accurately - it may be that there is a bug in 0.48 and it would be helpful to verify it.
