BUG/MINOR: proxy: preset the error message pointer to NULL in parse_new_proxy()

Browse source 
As reported by Coverity in issue #1568, a missing initialization of the
error message pointer in parse_new_proxy() may result in displaying garbage
or crashing in case of memory allocation error when trying to create a new
proxy on startup.

This should be backported to 2.4.
