Description:

Take this simple dispatcher script:

#!/bin/bash

INTERFACE=$1 # The interface which is brought up or down
STATUS=$2 # The new state of the interface

case "$STATUS" in
up) # $INTERFACE is up
su -c "DISPLAY=:0 dropboxd &" orschiro
;;
down) # $INTERFACE is down
;;
esac

All it does is to start dropbox daemon after a successful connection. The result is, however, that the dropbox tray icon appears for ~3 seconds before it disappears again.

A zombie process remains:

~ $ ps aux | grep dropbox
orschiro 779 0.0 0.0 0 0 tty1 Z Okt29 0:23 [dropbox] <defunct>

I doubt that this error is related to Dropbox only. For some reasons the dispatcher scripts seems to kill the executed process after while.
