Description Falk-Florian Henrich 2007-01-02 11:43:28 UTC

Installed from:    Fedora RPMs
OS:                Linux

When using the export to EPS feature, the resulting encapsulates PostScript file has a wrong bounding box value. In most cases the bounding box is too large, leaving a thick white border around the chart.
