Yes - my fault.
Thank you very much for this bug report, I missed the fact when
'mkdir' the temp root, it only has permissions for the current user.
Working on a fix right now, THANK YOU.

If you are fit using git, it's the best.
Otherwise, you can check the wiki for the diff. releases:
- stable RC builds
- autobuilds ..
I will update you when it's fixed. Would be great if you verify it afterwards.
