0.25 was released in April 2012. There have been a few point releases 
since but they only contain a few fixes that devs though where worth 
backporting.

The point is the problem you are reporting is fixed in newer versions so 
you either upgrade and get all the new fixes and new features or put up 
with your old buggy version.
