If I symbolicate the report then it points to this line

This is most likely related to ARC on 10.7, the Dialog plug-in was 
updated to ARC last month:

Do you have a build environment on 10.7? If so, it would be nice if you 
could insert an NSLog with all the objects involved in that line and see 
if anything pops out, and if the log statements are shown, i.e. that it 
actually is this line causing the crash.

ARC would cause objects involved in that line to be retained (I think), 
but that should also be safe, unless some of the objects are not 
actually objects, but I don’t see anything wrong there.

I don’t have 10.7 available myself.
