LSSetDefaultRoleHandlerForContentType in Yosemite
I am having a problem with the CF LSSetDefaultRoleHandlerForContentType function. This feature sets the application as the default viewer for the UTI type. In 10.9 it works without issue, but in the latest 10.10 build it doesn't work with return code -54. The doc and related forums did not help. All I have found about the problem is that -54 means permErr (Permission Error?) And that's it.
Perhaps someone experienced this problem and can help with some workaround? Thanks in advance!

As of OS X 10.10, Yosemite LSSetDefaultRoleHandlerForContentType
no longer works / is not allowed in sandboxed applications.

Also notice the console output when you try to use it:
