Comment 1 for bug 171500

From the release notes for 0.44 (released 2006-06-23):
«The unfinished path in Pen tool is now cancelled, not finalized, when you switch away from the Pen tool. Apart from being more intuitively correct, this also fixes a crash when you quit Inkscape with the unfinished path in Pen tool. »
