Comment 3 for bug 1638373

The files are completely different, here is what I found in /usr/share/inkscape/markers/markers.svg:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!--
NOTE: this file is currently (0.48+) edited manually.
Insert the new markers into the <defs>.
-->
<svg xmlns="http://www.w3.org/2000/svg">
 <defs id="defs3"><!-- Arrows --><!-- 1 LARGE --><!-- 1 Medium --><!-- 1 small --><!-- 2 LARGE --><!-- 2 Medium --><!-- 2 small --><!-- Tail --><!-- distance markers --><!-- round dots --><!-- squares --><!-- diamonds --><!-- diamonds placed at the start of the line --><!-- diamonds placed at the end of the line --><!-- empty diamonds --><!-- empty diamonds placed at the start of the line --><!-- empty diamonds placed at the end of the line --><!-- triangles --><!-- Empty Triangles --><!-- stops --><!-- filled semicircles --><!-- non-filled semicircles --><!-- scissors --><!-- Others --><!-- Infinite lines --></defs>
</svg>

I removed inkscape and install it again, but it's the same.
