A spread sheet with a grap theat reproduces the bug
Saving a chart in Calc crashes LibreOffice 5 when one tries to export it as image with EPS (Encapsulated PostScript) format using LO5 under Ubuntu Linux (I have not tried other OSs). It works perfectly under LO 188.8.131.52 .
To reproduce the problem open the spreadsheet annexed, select the chart and export as image. It will be exported as image in any format except EPS; the problem is that of all formats available for this purpose under LO 5 (and earlier) versions of Calc produce low quality images where lines and numbers are either fuzzy (like in jpeg files) or heavily pixelated and no good for publication. Not even Tiff or png formats render images in good quality when charts are exported from Calc.
Unconfirmed with v184.108.40.206 under ubuntu 14.04 x64.
Confirmed with v220.127.116.11 under ubuntu 14.04 x64.
Confirmed with v18.104.22.168 under mint 17.2 x64.
Resolved fixed with current build of master.
