Segmentation fault if an action is taken from the developer tools while device is locked

[ticky]

The program immediately segfaults if you do the following process;

1. Connect device, start ios_webkit_debug_proxy
2. Open debugger to an open page
3. Lock the device or allow it to lock automatically
4. Attempt to use the debugger

Running on Ubuntu 13.04 with libplist 1.10, libusbmuxd 1.0.8 and libimobiledevice 1.1.5.

I get the impression from the readme that ios_webkit_debug_proxy should be able to start with no devices attached, and survive disconnections and reconnections. Neither appear to be the case in the environment I'm using it in.
