           Summary: custom wallpaper script don't work in kdesktop
           Product: kdesktop
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal

         Component: general
        AssignedTo: unassigned-bugs kde org
        ReportedBy: figjina libero it


Version:            (using KDE 3.5.9)
Installed from:    Debian testing/unstable Packages

The following mywall.sh script works fine from konsole. It creates a random image with a gradient background, suitable for the desktop size. If I use it in kdesktop configuration with mywall.sh %x %y %f , it doesn't work and the desktop becomes a single color. I think that if it works in a terminal, it should also work in kdesktop.
Here's the script:

#!/bin/bash
WALLDIR=/path/to/wallpapers
XSIZE="$1" ; YSIZE="$2"
FILE=`find "$WALLDIR" -iname '*.jpg' ; find "$WALLDIR" -iname '*.png'`
FILE=`echo "$FILE" | sort -R | head -1`
if [ -z "$FILE" ] ; then exit 1 ; fi
echo "Converting $FILE"
convert -size "${XSIZE}"x"${YSIZE}" gradient:firebrick-gold -gravity center \
	\( "$FILE" -resize `expr ${XSIZE} - 40`x`expr ${YSIZE} - 60`'>' \) \
	-composite -flatten -quality 100 "$3"
