Hi Edwin.

from the stacktrace you provided, teh relevant part is this:

#0  -[NSString(NSStringDrawing) boundingRectWithSize:options:attributes:] (self=0xb7fdfad8 
<.objc_str476>, _cmd=0xb7e0d040 <.objc_selector_list+240>,
    size=..., options=NSStringDrawingUsesLineFragmentOrigin, attrs=0x8a723c8) 
at NSStringDrawing.m:683
#1  0xb7b7430e in -[NSString(NSStringDrawing) sizeWithAttributes:] (self=0xb7fdfad8 
<.objc_str476>, _cmd=0xb7fdfb80 <.objc_selector_list+144>,
    attrs=0x8a723c8) at NSStringDrawing.m:673
#2  0xb7f6824f in +[FSNBrowserCell initialize] (self=0xb7fdfa40 
<_OBJC_CLASS_FSNBrowserCell>, _cmd=0x8223d40) at FSNBrowserCell.m:87



I'm unsure what is happening here. Either fontAttr is returning soemthing  null 
and you are on a platform where getting .width out of null generates a 
stacktrace, but that would be typical of sparc, not x86.

The second question is however how that could  happen.

      fontAttr = [NSDictionary dictionaryWithObject: [NSFont systemFontOfSize: 
12]
                                             forKey: NSFontAttributeName];

Should always return soemthing meaningful, I suppose? It's asking for the size 
12 system font, something extremely standard!

Could you put a breakpoint there and print fontAttr?



Then it does:

dtslenght = [dots sizeWithAttributes: fontAttr].width;

where dots is a:
static NSString *dots = @"...";

which looks quite reasonable for me. A static string, no fancy characters.
