Problem with scheduled snapshots

HI I’m getting problems with scheduled snapshots after recent update, I see similar problem was reported with scrubs. Is it fixed? How can I update my system?

Traceback (most recent call last):
File “/usr/lib64/python2.7/logging/”, line 76, in emit
if self.shouldRollover(record):
File “/usr/lib64/python2.7/logging/”, line 154, in shouldRollover

record.message = record.getMessage()
