Hi Riccardo,
could you please explain what you mean by "hang"?
Hang means that the preview of the font does not change (the previosuly
selected font remains). The application stops to respond to any click.
It redraws windows and controls though (no white/black spots)
And did you get the same stack trace after continuing your application
for some time and then stopping it again?
No I just waited for a long time.
The line your reported stack trace is in looks rather harmless:
CGFloat f_ascender = [f ascender], f_descender = -[f descender];
If the printouts do not seem suspect to you.... I don't know.
I tried today again and get a different stacktrace:

up at #6 I can:
(gdb) po self
Terminal Roman 12 PT{NSColor = "{ ColorSpace = \"NSNamedColorSpace\";
Catalog = \"System\"; Color = \"textColor\"; }"; NSFont = "<NSFont:
0xb7c35d88> Terminal 12.000 0.000 0.000 12.000 0.000 0.000 P 0";
NSParagraphStyle = "<NSMutableParagraphStyle: 0xb7c16da8> Alignment: 2
LineSpacing: 0.000000 ParagraphSpacing: 0.000000 LineBreakMode: 0"; }
which means it is draing the preview string of the "Terminal" font
I hit continue, wait 5 minutes:

It is still trying to print the same string!
After a couple of minutes:

Which is our original stacktrace. So this code is looping without doing
anything.
Sorry for being of no help here,
I never seem to have easy problems, sorry!
