I'm having the same problem, but with different symptoms. I have tried chmod-ing and moving alfred preferences folder, to know avail and I was able to create a hello in my /tmp as above, but i still get the following line in console when trying to add a worfklow:
1/7/16 2:11:22.428 PM CoreServicesUIAgent[566]: Error -60005 creating authorization
It seems like a permissions thing, but wouldn't chmod resolve that?
Thanks in advance for any help!
