Dear Maintainer,


Files related to bugreport are attached in: GraphvizBugreport.zip


I discovered that one edge was missing when generating
PNG from dot file. See: broken.dot, broken.png

There should be edge linking SampleSuperClass to SampleClass.
It is declared in dot file on line: 104.

If I just remove: style="tapered"
Edge appears.

See: workaround.dot, workaround.png

This style is valid and is succesfully used in another edge, earlier in the
file.
It should not cause disappearance of the endge, so it must be bug.
