Comment 5 for bug 790677

Not reproduced with your example file either (Inkscape 0.48.0, 0.48.1 and 0.48+devel r10244, OS X 10.5.8 (i386), with custom as well as default settings, no tablet).

- Does it also happen if you extract a handle from a cusp node without handles (create a path with the bézier tool using single clicks - without click-dragging) or only when extracting a handle immediately after retracting it?
- Do you use an extended input device (tablet w/ pen)?
- Could you produce a backtrace (with debugging symbols for Inkscape installed)?
