I have just noticed that inkscape-0.46 has been removed from the tree. Please reconsider this removal as I experience a segfault regression as reported here: https://bugs.launchpad.net/inkscape/+bug/511577 The regression has been confirmed. This problem is not present with version 0.46.
The bug has been fixed and is going to be released with 0.48.1. In the meantime I have extracted the patch for 0.48.0
Created attachment 252249 [details, diff] inkscape-0.48.0-sp_shape_segfault.diff Here is the patch
inkscape-0.48.1 has been proposed for stabilization in bug 387199; that would resolve this as well.
