preview of eps files in konqueror

Hi, I use Suse pro 9.0 with its kde 3.1.4. When I manage my eps files (created with Mathematica) I get a strange preview in Konqueror: instead of showing the data according to the BoundigBox, white Icons are displayed with the (almost invisible) data in the lower left corner. Of corse the file haeder is correct and the files are displayed in ghostview according to the BoundingBox (without white frames or so...) This did not happen in my old Distros ( 7.x and before), AND: the same files show a correct preview in Konqueror of KDE 3.1.4 with Debian. So, what is wrong with SuSE??? Thanks for your help, Felix
