Comment 3 for bug 438141

Ok, those values seem to be the problem. My (old) inkscape settings contain the following values:
      <eventcontext
         id="arc"
         style="fill:red;"
         end="3.0991159e-12"
         start="5.3972858e-16"
         usecurrent="1"
         open="0" />

If the start- and end-attribute is set to "0", everything works fine.

Cheers
Volker
