I use the python JIRA api to query issues in a test harness. After upgrading from python2.7.6 to 2.7.10, when the program exits, I get
Exception AttributeError: "'NoneType' object has no attribute 'version_info'" in <bound method JIRA.__del__ of <jira.client.JIRA object at 0x7f427eedf490>> ignored
If I just load the module in the interpreter, then exit, it generates the exception.
