This command line does not work on Jaunty:

 GPL Ghostscript 8.70: Unrecoverable error, exit code 1
 convert: Postscript delegate failed `foo.pdf': No such file or directory @ pdf.c/ReadPDFImage/612.
 convert: missing an image filename `ppm:foo.ppm' @ convert.c/ConvertImageCommand/2775.
 nmn@laptop:~/temp$
The problem is in "-define pdf:use-cropbox=true" option. Without this option everything works Ok. Workaround is quite simple and may be done on per-user basis, whithout root privileges. You can overwrite stock convertDefault.py by placing your own script with same name into ~/.lyx/scripts directory. I attach fixed convertDefault.py that works for me.
