nfsen does not produce graphs properly
Netflow visualisation and investigation tool

Nfsen creates graphs but does not render fonts properly. This is nfsen v1.3.2 on FreeBSD 8.2-RELEASE. Attached is an example graph. Graphing using 'rrdtool graph' by hand works fine and produces a properly font-rendered graph. Attached is an example of the broken graphs. Instead of letters and numbers correctly rendered with fonts, all I get are empty boxes.
