[iOS 8]WebKit Threading Violation - initial use of WebKit from a secondary thread

[yezilife]

I updated Ruby to 1.2.4 and Xcode to 6.1, and tuneup js to latest version, then I try to use the auotomation, but got following error:

Launching instruments. Will retry 0 more times if it doesn't initialize

2014-10-29 15:47:33.674 instruments[64570:249034] WebKit Threading Violation - initial use of WebKit from a secondary thread.
Instruments Trace Error : Target failed to run: The operation couldn’t be completed. (FBSOpenApplicationErrorDomain error 4.) : Failed to launch process with bundle identifier

any idea? Thanks.

I am also seeing "Launching instruments. Will retry 0 more times if it doesn't initialize".
