finding memory leaks

...surely a FAQ but I am a bit struggling with it over this code

 http://nopaste.ch/1685f5d17a92cfd.html

For this snippet there is nothing that should live on after the blocks has finished. So no "retain" and things should be quite straight forward. With the NSAutoreleasePool I just find it hard to find out what needs to the "autorelease"'d and what not. ("alloc", "new" etc are already covered - I know) But somehow I am still failing according to "leaks".

I need some help here to interpret this output. I have absolutely no clue where the leaking strings are coming from. First though "stringByTrimmingCharactersInSet" (line 14) but that does not like to be autorelease'd. And for the ABSearchElementConjunction that looks like searchElementForConjunction:children (line 47) needs an autorelease. But when I do add it - the app crashes.

Any help appreciated.

cheers
