I don't think that is the problem. The problem is that NSRect is not an NSObject-based object, but a C struct and po may not work properly with structs, as according to the docs of LLDB po prints out the description of a ObjC description.

You can check that here (search for NSRect):

https://developer.apple.com/library/mac/documentation/cocoa/reference/foundation/miscellaneous/Foundation_DataTypes/Reference/reference.html

and here (search for po):

http://lldb.llvm.org/lldb-gdb.html
