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.
}
