Public bug reported:
Binary package hint: imagemagick
Recently I moved from 9.04 to 9.10 and found that lyx does not show pdf
graphics anymore. The "Error converting loadable format" messages are
displayed instead pdf graphics.
Reproducing this bug is very simple, just open lyx, create new file and
insert pdf graphics.
I found that LyX uses 'convert' command from imagemagick to convert pdf
to ppm file. This command is called from
/usr/share/lyx/scripts/convertDefault.py script. It is called with
following arguments:
convert -define pdf:use-cropbox=true -depth 8 -flatten "pdf:foo.pdf"
"ppm:foo.ppm"
This command line does not work on Jaunty:
n...@laptop:~/temp$ convert -define pdf:use-cropbox=true -depth 8 -flatten
"pdf:foo.pdf" "ppm:foo.ppm"

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.
