BLANK Schermo degli strumenti quando si utilizza 'Time Profiler'. Ultima build di Xcode 6

Question

Pochi giorni fa, "time profiler" ha smesso di funzionare. Altri strumenti funzionano ancora ... core animation, allocazioni, ecc. Il time profiler è solo uno schermo vuoto. Nessuna chiamata di funzione mostrata, nessun grafico, niente. Stesso risultato per più progetti.

Ho appena reinstallato Xcode (su se stesso). Stesso problema. Non riesco a trovare nessun file di preferenze che possa essere eliminato per gli strumenti. Ho davvero bisogno di questo per funzionare. Non ho davvero il tempo di reinstallare l'intero sistema operativo.

AIUTO

Edit: eliminazione com.apple.dt.instruments.plist non cambia nulla. Trovato questi registri in Console dagli strumenti (sotto). Sembra che stia succedendo qualcosa di divertente, e probabilmente vale la pena sottoporre un bug ad Apple. Per ora, la domanda è: come posso riportare lo stato degli strumenti a quello che dovrebbe essere?

Will attempt to recover by breaking constraint

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, break on objc_exception_throw to catch this in the debugger.
