Comment 8 for bug 540591

Patch tested on Windows XP, Inkscape trunk rev. 14968.

The crash is fixed, but the LPE curve doesn't apply to the path when reaching step 8.

A console message shows at step 7 (Document was modified while being updated after undo operation), and an empty line is added in the Undo history dialog when clicking again on "Draw path" after step 8 (the console then shows a "Incomplete undo transaction" warning).
