crash in GUI / ProjectCenter

Hi,

I am able to produce a crash in ProjectCenter, by opening a project, 
selecting a file to edit and then closing the project. If I just open 
and close a project, nothing happens. So it appears to depend by the 
presence of the editor.

I noticed this on my Rasperry PI so arm6, but now I can reproduce it on 
x86-64 too. Hmm.

106       // Check with delegate for hit rect...
107       if (_delegate && [_delegate respondsToSelector: selector])

(gdb) p _delegate
$1 = (struct objc_object *) 0x3161e8

if I po _delegate, then I get a crash, appears it is not valid.


I try to understand if this is more a GUI or a ProjectCenter issueq
