Ok, I think I've narrowed it down.
This bug may be a shortcut conflict in Qt introduced with the following
revision:
https://code.google.com/p/spyderlib/source/detail?r=d703c90266fa
This is very surprising but it's apparently causing a hard crash.
So, to confirm that this is it, could you please try and comment lines
631-634 in spyderlib\widgets\editor.py:
self.zoominsc = newsc(QKeySequence.ZoomIn,
lambda: self.emit(SIGNAL('zoom_in()')))
self.zoomoutsc = newsc(QKeySequence.ZoomOut,
lambda: self.emit(SIGNAL('zoom_out()')))
(and uncomment the lines in IPython\qt\console\console_widget.py, of course)
Thanks,
-Pierre
