I have probably found a problem with Dia port: if I try to export a diagram in png format the program do not recognize the height of the image and it gives an error: libpng error: Image width or height is zero in IHDR If I specify the height of the image the program cores dump: Floating point exception (core dumped) I do not know if this is a dia problem or a png one. Cheers Giovanni
