title: Exception Type: EXC_BAD_ACCESS (SIGBUS)
body: <p>The Imagepair object is a member variable of some other class.. I want its members to be changed, every time I call the getImageURLs-function (requests a web page and parses its elements). The first time it works fine, but if I call the function a 2nd time on the same object, the application crashes and leaves me with a EXC_BAC_ACCESS Exception. My guess is, that I am doing something wrong with the memory management, but I cannot figure out what, as I've got a background in Java and am not really used to doing the memory management manually.</p>
