> Does this patch help? No. I checked that QDir::currentPath is /tmp/lyx_tmpdir270589aB5uF/lyx_tmpbuf0, command is
epstopdf --outfile='20_usr_local_share_lyx16_doc_clipart_escher-lsd.pdf' '20_usr_local_share_lyx16_doc_clipart_escher-lsd.eps' which runs fine outside of lyx. So the problem seems to be with process.exitCode() (which is 255) (or the waiting process). Bo
