GWorkspace crash when renaming a tab

[Riccardo Mottola]

Hello,

I get the attached stacktrace when renaming a tab in GWorkspace. I 
wonder where it comes from:

TSHelfWin.m:408 just creates and then autoreleases the dialog.

The line from SympleDialog (defined in Dialog.m) is:
- (void)dealloc
{
  [super dealloc];
}

The line from NSWindow is:
  if (_windowNum)
    {
      [self _terminateBackendWindow];
    }

so everything looks pretty simple.  Why is 
_terminateBackendWindowFailing? becuase self doesn't exist anymore? This 
is strange.

IN any case I tried instead of autoreleasing the dialog immediately, to 
change TShelfWin.m in:

  result = [dialog runModal];
  [dialog release];

And it works.

Do you think it is a good idea? I suppose that during runModal the 
autoreleasepool got emptied, but I don't fully understand.
