Hey,

I tracked down the problem to be a ghostscript problem... when i run the 
convert command as root it works fine... but as apache (or any other 
user) it gives me this error:

command: gs -q -dBATCH -dSAFER -dNOPAUSE 
-sOutputFile="item137796_1.pdf.jpg" -sDEVICE=jpeg -f"item137796_1.pdf"

Error: /undefinedfilename in (item137796_1.pdf)
Operand stack:

Current allocation mode is local
Last OS error: 2
GPL Ghostscript 8.54: Unrecoverable error, exit code 1

And as i said before... as the root user the command works fine...

Also posted this on the gs mailinglist, but not very responsive over there
