Re: new crash: TalkSoup startup

[Fred Kiefer]

Hi Riccardo,

first off, the exception you are getting seems to be happening in the [NSLock 
new] call and this is highly unlikely. Could you please verify that you are 
using versions of gun and base that fit properly together? Or maybe you have 
local changes to base?

Even for not document based applications GNUstep initialises an 
NSDocumentController, if that gets used in the code. You have a valid point 
here to question that. Maybe somebody should do a bit of research, wether Cocoa 
does the same. At the moment we read the document class definitions inside the 
NSDocumentController initialisation code and only after that we know whether we 
have a document based application.

In your specific case the initialisation of the NSDocumentController happens 
because NSApplication cannot find a suitable responder for an action it is 
trying to send. This looks like your UI is using an undefined message.

Sorry, I know that this isn’t much help. But it is the best I can do right now.
Fred
