Exception raised during xib loading

When I ran StepChat on gnustep and I set to load the MainMenu.xib instead of MainMenu.gorm, an expception is raised with this message on the termianl:

2013-11-29 13:08:25.720 StepChat[8164]Is not possible to load the model file 'MainMenu'

2013-11-29 13:08:25.750 StepChat[8164] /usr/GNUstep/Local/Library/Headers/GNUstepBase/GSIArray.h:549 Assertion failed in GSIArrayItem GSIArrayItemAtIndex(GSIArray, unsigned int). NSInvalidArgumentException

2013-11-29 13:08:25.750 StepChat[8164] Problem posting notification: <NSException: 0x121cd40> NAME:NSInternalInconsistencyException REASON:/usr/GNUstep/Local/Library/Headers/GNUstepBase/GSIArray.h:549 Assertion failed in GSIArrayItem GSIArrayItemAtIndex(GSIArray, unsigned int). NSInvalidArgumentException INFO:(null)

Note: I implemented the .xib on OS X (10.7, 10.9)

I made a backtrack and I attach here;

as you can see the aClass is nil, however in the backtrack log I made, there are also the commands I ran to debug and see what is the problem.

I don't remember if the netiquette want to attach the file and also post here the file content; to be sure I post also the file content here, but please notice me if I shouldn't do.

Cheers,
Alex (Slex)
