I tried your second line being on x86 32, but it did not work I got a 
syntax error

(gdb) po ((id*)%ebx)[5]
A syntax error in expression, near `%ebx)[5]'.

I then searched and found this:
http://www.clarkcox.com/blog/2009/02/04/inspecting-obj-c-parameters-in-gdb/

Not knowing if I am before or after a prolog, I tried both.

(gdb) po *(id*)($esp + 8)
-> invalid

(gdb) po *(id*)($ebp + 16)
file://localhost/Users/multix/Pictures/02Trieste_Linhof_R80S.jpg

Since I put a breakpoint here:
(gdb) bt
#0  0x920b4fd1 in -[NSDocumentController noteNewRecentDocumentURL:] ()
#1  0x91f9c4b3 in -[NSDocumentController 
_finishOpeningDocument:andShowWindows:] ()

it means that I have an apparently valid file! this makes things even 
more strange! And I have even less clues on how it is going wrong. If I 
have AppKit manage its menu and the File is there (I suspected it was 
empty), what could go wrong?

One think I'd like to check is the type of object, that is, being a a 
File (wrong, old code) or an URL containing a file.

I did:
(gdb) po [*(id*)($ebp + 16) class]
NSURL

so it looks "correct" to me!

Further ideas? Thank you.
