I need to "quit" Ghostscript at this time to get:
convert.exe: no decode delegate for this image format `<file name is
here>.ps'.
convert.exe: missing an image filename `ppm:<file name is here>.ppm'.
C:/LyX/LyX1.4.2/Resources/scripts/convertDefault.sh ERROR
Execution of "convert" failed.
Whereas when the image previews ok the last few lines in the debug
window are:
ForkedCallQueue: waking up
LoaderQueue: I'm going to sleep
ForkedCallQueue: I'm going to sleep
Image conversion succeeded.
Loading image.
Image loading succeeded.

It appears that "Image conversion succeeded" does not appear when the
image does not show in Lyx. It also look like that having the file deep
in a long tree of subdirectories contributes to this problem as the same
file work fine when placed in C:\ directory.
Why I only have this problem with one particular figure is still very
puzzling.
When LyX needs to display your image, it calls the convertDefault.sh
script, which in turn calls ImageMagick's convert.exe program to convert
test.ps to test.ppm. ImageMagick then uses Ghostscript to read the .ps
file. Judging by the fact that Ghostscript "hangs open" until you close
it, and the "missing filename" bit later on, it looks to me as if the
ImageMagick-to-Ghostscript call might somehow have lost or mangled the
file name (?!). There's some relevant output just above the first line
you quoted that would help.
If you want to investigate this possibility, try the following. In the
LyX Resources\scripts, find convertDefault.sh and open it with a text
editor (e.g., notepad). Find the lines
# converts an image from $1 to $2 format
convert -depth 8 "$1" "$2" || {
and insert
echo "Converting $1 to $2 ..."
between them. Then run with -dbg graphics again. You should get output
similar to what I got (albeit with different paths):
No converter defined! I use convertDefault.sh
sh "C:/Program
Files/LyX142/Resources/scripts/convertDefault.sh" "eps:C:
/Documents and Settings/<your id here>/Desktop/test.ps"
"ppm:C:/Temp/lyx_tmpdir5
620a03976/test5620a03976.ppm"
ForkedCallQueue: waking up

:/Temp/lyx_tmpdir5620a03976/test5620a03976.ppm ...

Image conversion succeeded.
Do the file names and paths look right when you do this?
