Running Apple Instruments from command line throws: The simulated application quit

Question

This popup prevent other scripts from running and prints the following:

instruments[2596] : kCGErrorInvalidConnection: CGSGetCurrentCursorLocation: Invalid connection instruments[2596] : kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

Segmentation fault: 11

I use subprocess (in python) to run number of scripts for testing my app.

Is it a bug in instruments? cause sometimes it just print to log a debug event: "The target application appears to have died", which doesn't stop scripts flow.

Any ideas?

[Edit]

I've updated yesterday command line tools and it seems to provide more details now:

[__NSCFType transport]: unrecognized selector sent to instance 0x7fa54ba61b50

You need to use the .app file in the iPhone simulator directory.

(or)

Do an xcodebuild with DSTROOT flag to deposit the app and use that for the automation.

xcodebuild -workspace ./ProjectWorkspace.xcworkspace -scheme "SchemeName" -sdk 
iphonesimulator5.1 -configuration "Debug" clean build install 
DSTROOT=~/Desktop/tmp/yourAppName.app
