CSPOT remote WooFPut segfault when target woof does not exist

[garethgeorge]

When running
idx = woof.put("woof://localhost:53933/%s/%s" % (funcname, constants.WOOF_NAME), constants.HANDLER_NAME, elstr). Once the target woof has been created, the application no longer segfaults.

the backtrace from gdb is

(the rest of the trace continues into the depths of the python interpreter so I have omitted it)
