This isn't likely to help. (It will help if and only if hostname aborts or returns a host name containing whitespace characters.)

The problem shown in the trace is that the operand passed to the script (sun) is not a choice in the case statement. Therefore, the client_home variable is never set and the following test to determine if $client_home expands to the name of a directory gets a syntax error.

The change I suggested in post #2 in this thread short-circuits the problem by exiting immediately if client_home will not be set by the given operand.
