closed subpaths and stroke-dasharray
A path is composed out of two closed supaths, representing
two squares.
This works without stroke-dasharray, but with stroke-dasharray Opera9
(builds 181, 197, 225, 229, ok up to 1670, which have other errors
explained in other errors reports) presents something different.
If something red is getting visible, an error occured.
Looks like a wrong close from the second z to the first
M, ignoring that this path contains two subpathes, each
of them closed separately. Note that stroke-dasharray is
only a stroke pattern, this means, it is not possible that
it is outside the stroke.
