Hi,
great! Feel free to contact me via Jabber (same as mail address),
should you run into any issues.
Attached is the backtrace leading up to NSClassSwapper, as Germán
requested.

Hi,
I'm actually not porting the code - I'm writing a Wine-like
emulation layer called Darling to run OS X apps directly. This fact
makes debugging slightly more difficult, but you're welcome to take
a look at http://github.com/LubosD/darling. [2]
I find the bug straightforward, class swapping should happen
before action/target binding, but I may be wrong indeed.
Germán, I'll mail a longer backtrace as soon as possible.

Hi Luboš,
I'm not too familiar with nib loading internals, but I will try
to take a look. Could you upload your work in progress code
somewhere? (Or do you have any changes to the original Mac
source?)
Cool idea to port the unarchiver. :-)
Cheers,
Eric

Hi,
I'm still working on getting the latest The Unarchiver for OS
X working under GNUstep/Darling/Linux and I'm seeing crashes
after the application's NIB file is loaded.
Now I'm sort of helpless. The crash happens when using the
target of a certain NSMenuItem.
You can see an excerpt of the relevant NIB's source here; the
NSMenuItem clearly refers to the NSPopUpButtonCell that it is
part of:

_popUpItemAction:
(Full code can be found in The Unarchiver's source tarball in
MainMenu.nib/designable.nib)
I can see the target being set correctly via -setTarget upon
loading:
