Found out something: You cannot catch any exception thrown in 
the listen()-method in general.

Chances are it's invoked in another thread and thus you can't 
catch it like that.

To sum it up.

Ex.

void thisFunctionThrows() { ... }

void ableToCatch() {
    try {
        thisFunctionThrows();
    }
    catch (Exception e) {
        // We can catch the exception ...
    }
}

void notAbleToCatch() {
    try {
        spawn(&thisFunctionThrows);
    }
    catch (Exception e) {
        // We cannot catch the exception ...
    }
}

void ableToCatchToo() {
    spawn(&ableToCatch); // We're able to handle the exception, 
because the try/catch is handled in the thread that calls the 
function that throws.
}
