Porting Help

[Lief Sinolumat]

Hi.

Looking for a little help porting and app over from Cocoa ...

The story so far:

I converted the nibs with nib2gmodel was able to load them up in GORM. The app 
has a few custom classes which GORM was able to figure out parsing the header 
files.  Basically only the menu had to be rearranged to conform to the GNUstep 
standard.  Pretty painless.

Some minor fiddling later, everything compiles but the app promptly crashes on 
a missing font (should this happen?). Fixed.

Now the app runs, but dumps core on the following method:

static void PSdecorateLine(float y, float w, float hg)
{
        [WhiteColor set];
        [NSBezierPath setDefaultLineWidth:1.0];
        [NSBezierPath strokeLineFromPoint:NSMakePoint(0.0, y-2)
                toPoint:NSMakePoint(w, y-2)];
        [[NSColor darkGrayColor] set];
        [NSBezierPath strokeLineFromPoint:NSMakePoint(0.0, y+hg)
                toPoint:NSMakePoint(w, y+hg)];
}

Anyone know what's going on here?  I'll admit I'm not too up on this PS drawing 
stuff.

Thanks
