Building Slony-I-concept.pdf gives me this:

ESP Ghostscript 815.01: Unrecoverable error, exit code 1
make[3]: *** [Slony-I-concept.pdf] Fehler 1

The problem seems to lie in figure-1.pic, because the generated document
is cut off exactly before that figure.

I have groff 1.18.1.1 and ghostscript 8.15.  Viewing the ps file through
gv results in the same error, so perhaps groff generates invalid output.

Any ideas?
