Comment 56 for bug 1282542

Having this issue in Linux Mint 17.2 for a few days now and it completely prevents me from applying updates with mint update manager... (tried selecting different individual packages each time hoping the bug affected one of them and not the whole process but it doesn't matter)

Is there a workaround I can try like reinstalling the affected package from a PPA or something? I have security updates pending from this and this has started to worry me :(
