minor bug report..

[komtanoo.pinpimai at livetext.com]

Hi All,

Right now, I'm trying to use the latest MogileFS from trunk, but I'm not
able to add domain, it always complains "Unable to retrieve domains from
trackers". I traced some codes and found that in "Backend.pm",

*_debug = *MogileFS::Client::_debug;

should be lifted to the head of the file or at least above do_request
otherwise do_request will fail because it calls _debug, which has already
been moved to MogileFS::Client, and it's not initialized yet at that
point. I guess there is an exception handler covers do_request so it won't
return the real error message, but the default one which is misleading.
