python-mysqldb: always connects to localhost ignoring host entry in option file (mysql_real_connect)

Hi,
Alan Krempler reported an issue with python-mysqldb package and Peter Pentchev kindly proposed a patch for the mysql_real_connect() function (as problem seems to come from it).

Please see the #921599 Debian bug report that I am linking to this issue.

Georg Richter Can you please review it?
