Window problem: avoid the GDNC console window

[Lloyd Dupont]

Every now and again (basically mainly when I create an NSTextAttachment of 
Image type) I get a GDNC console window which pops-up over my application, 
i.e. a black and white DOS console without prompt and titled "GDNC" appears 
over my application.

I would like to remove this: Awfull, Invasive, Irritating and Most 
Importantly: USER CONFUSING windows.

Now someone told me about a hack I have to write somewhere to avoid it.
I didn't pay attention at the time to the fact that every time I SVN update 
the hack would be deleted.... and I forgot to write it somewhere along the 
TODO every time I SVN update.

Could someone kindly remind me what I should hack to launch (this apparently 
useless...) window?

Note: I'm not runnning an NSAppplication (one is instantiated as it was 
apparently needed to use NSFont, but I'm writing a .NET app and GNUstep is 
used only for "data storage")
