Bug#352173: missing vertical lines in printed documents, gs-esp 8.15.1.dfsg.1-1

[Nils <linuxuser@knabber.homelinux.net>]

Package: gs-esp
Version: 8.15.1.dfsg.1-1

Documents which contain vertical lines are not correctly printed, because the 
vertical lines are missing at some parts. It's working fine with gs-esp 
7.07.1-9 and gs-afpl 8.14-3. 
You can reproduce the problem with the hpijs driver (any driver?) and page 19 
of this document: http://md.hudora.de/presentations/wehrmann-xss.pdf
I use debian etch, but it seems that the problem only depends on the gs 
version.
