According to documentation, HistoryAccessor.get_session_info(0) should return information about current session. Instead, it throws exception.

When providing session number everything works as expected:
In [6]: h.get_session_info(session=102)
Out[6]: (102, datetime.datetime(2014, 3, 13, 9, 30, 57, 524807), None, None, u'')
As a workaround, to get current session, I'm using get_tail(n=1):
for x in h.get_tail(n=1):
session = x[0]
