Re: PikoPixel hangs on startup

[Riccardo Mottola]

Hi,

some more information:

I put a breakpoint:

Breakpoint 1, -[NSView setFrame:] (self=0x89ab408, _cmd=0xb7fab2a8 
<.objc_selector_list+376>, frameRect=...) at NSView.m:1188
1188          NSWarnMLog(@"given negative height");

The stacktrace I get is below. It looks as it comes from Nibloading 
itself, thus I wonder what is different from other setups.

Here the frame:
(gdb) p frameRect
$1 = {origin = {x = 1, y = 9}, size = {width = 174, height = -13}}

Indeed, negative!

I went up the trace:
#4  0xb7df5644 in -[NSWindowTemplate nibInstantiate] (self=0x89ab358, 
_cmd=<optimized out>) at GSNibLoading.m:508
508           [_realObject setFrame: [NSWindow 
frameRectForContentRect: [self windowRect]
(gdb) po [self title]
Preview

Thus, the issue seems to be the Preview window.

Fred, do you think it could be a decoration issue problem or something 
like that? The preview is different style, right?
