I set a breakpoint there and continued until the window had the title
Preview.

(gdb) p contentRect
$2 = {origin = {x = 0, y = 0}, size = {width = 106.186996, height = -13}}

it appears to be already called that way!

I go up twice and see this:
(gdb) up
#2  0xb7df460b in -[NSWindowTemplate nibInstantiate] (self=0x8a52d50,
_cmd=<optimized out>) at GSNibLoading.m:500
500           [_realObject setContentMinSize: _minSize];
(gdb) p _minSize
$4 = {width = 106.186996, height = -13}

I am not sure, but it seems that _minSize is set to contentMinSize in
the designated Initializer. I tried putting a breakpoint in line 318 of
GSNibLoading.m but it is apparently never reached.

The proof is this:
(gdb) p _minSize
$8 = {width = 106.186996, height = -13}
(gdb) p [window contentMinSize].height
$9 = 1

The initializer code sets them to the same value. Fred, what does your
widsom say?
