Getting exception since update from 6.5.1.2 to 6.5.2

[Andreas Herz]

I just updated offlineimap to 6.5.2 with the gentoo ebuild and now i get
this exception with my account:

Thread 'Account sync KVA' terminated with exception:
Traceback (most recent call last):

    sleepresult = self.ui.sleep(refreshperiod, self)
  File "/usr/lib64/python2.7/site-packages/offlineimap/ui/UIBase.py", line 479, in sleep
    abortsleep = self.sleeping(10, sleepsecs)
  File "/usr/lib64/python2.7/site-packages/offlineimap/ui/TTY.py", line 101, in sleeping
    time.sleep(sleepsecs)
NameError: global name 'time' is not defined

What would be the best way to help with debugging?
