For those of you who don't want to upgrade to 1.0.3, here are some simple steps you can do to make ZD work again on Snow Leopard:

2) Copy libzimbra-native.jnilib to <ZD installation directory>/lib, replacing the existing libzimbra-native.jnilib file)
3) Using a text editor (e.g. vi), open <ZD Installation directory>/zdesktop, look for a line like this:
change this line to:
if [ "$ver_minor" -gt "5" ]; then
save the change and close the file.
if [ "$ver_minor" -gt "6" ]; then
4) Start Zimbra Desktop
