Comment 7 for bug 1379471

I would almost guarantee it is the same issue. I had the same exact behavior that you descibed. There has not been a new release of xfconf so unless canonical(ubuntu) cherry picked the commit to xfconf that fixes it, it will still be broken and my bets are that they didn't. Your only option is to recompile xfconf yourself either from git or from ubuntu's sources and apply the patch yourself from my bug eric linked before. You could possibly make a bug report with ubuntu and link them to the patch and hope they pick it and update the package.
