TypeError: Cannot read property 'on' of undefined

Similar to #175

I get an error message box containing a stack trace when trying to debug my application with gdb.

launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Rust",
            "type": "gdb",
            "request": "launch",
            "target": "target/debug/redis-test"
        }
    ]
}

Stack Trace:
