Clear Cache not working on 2.1.4

[Freud]

In cmsms 2.1.4 Clear Cache does not delete any file from the folders tmp/cache and tmp/templates_c.
It does work normaly in cmsms 2.1.3, but not in a fresh install of 2.1.4 or in an upgrade from 2.1.3 to 2.1.4.
I cannot figger out what's going wrong, not even with debug=true in the config-file.
Strange enough I accedentally discovered that Clear Cache works normaly when saving the User Preferences first.
Of course all this can be tackled by deleting all the files from the folders manually, but it should be working in the backend.

This is a known bug and will be fixed in the next release.

I am getting same issue with no fix at all.

Updating cmsms to 2.1.5 fixed it for me
