This is a known bug. Please see the bug report here:

I think you need to upgrade your glib. Please add a message to the ticket if upgrading glib works for you; ultimately we need to request the glib maintainer to upgrade the official glib package in Ubuntu to a newer version to make this easier for everyone.
