Hi Mirko
For svg fill, line pattern fill and point fill, Qt needs an x-server for
printing to pdf (therefore the crash).
Two workarounds are possible:
- Print composition as raster (in that case, the whole content is
printed to a QImage first)
- Run an x-server on the server machine.
Regards,
Marco
