As you're sending the output to a file, why not just?:

system q[perl -d:CallTrace i-Mage.pl 2> trace.txt];

    Well I shall probably have to do that, But then when it segfaults I wont be able to manage the crash, It'll just be a case of restarting the application. I suppose since I have a crash file (the trace.txt), I can look for trace.txt files at the startup of a programme and then do whatever I need to.

      It would be no different if you used open3(). That also starts a separate process over which you would have no control.

        Well, with open3(), I can use waitpid and then read (error); which allows me some control over what happens next, if I just did 

        
system ("perl -d:CallTrace Foo.pl");

        Wouldn't it just crash? Maybe not, I should probably try it.
