CFNetwork WebCore Crash
===

I'm getting some crash reports from the App Store that I can't really follow. So the thread always crash like this

    0	 libobjc.A.dylib	
    objc_msgSend + 15
    1	 CFNetwork ✭	
    HostBase::lock() + 14
    2	 CFNetwork	
    DispatchHost::performInvocation(void const*) + 12
    3	 CFNetwork	
    __setupTCPConnection_block_invoke_2 + 290
    4
    ...
    libsystem_network.dylib	
    __tcp_connection_notify_complete_block_invoke_1 + 18
    5	 libdispatch.dylib	
    _dispatch_call_block_and_release + 12
    6	 libdispatch.dylib	
    _dispatch_worker_thread2 + 258
    7	 libsystem_c.dylib	
    _pthread_wqthread + 294

I have like 14 of these crashes. The only thing they have in common is this other thread.

    ...
    libsystem_kernel.dylib	
    mach_msg_trap + 20
    1	 CoreFoundation	
    __CFRunLoopServiceMachPort + 126
    2	 CoreFoundation	
    __CFRunLoopRun + 882
    3	 CoreFoundation	
    CFRunLoopRunSpecific + 300
    4	 CoreFoundation	
    CFRunLoopRunInMode + 104
    5	 WebCore	
    WebCore::runLoaderThread(void*) + 128
    6	 libsystem_c.dylib	
    _pthread_start + 320

I use UIWebViews in my app (although not intensively. IS WebCore only called when using webViews? Or can this be relted to something else?

I can't replicate in my device. Any idea will be much appreciated. 

Thank you!
