[Bug 210882] Re: sshfs crashed with SIGSEGV in g_slice_alloc()

[Kees Cook]

** Description changed:

  I looked at other crash reports where it was seems to be similar. I can
  reproduce the error and this is not the same as it was described in
  other similar/related bugs.
  
  Today I tried a Xinerama using a notebook (Intel 945GM) as main monitor
  and a LCD as left-on monitor.  I'm using the (old) i810 driver, because
  it works.  Two separated screens (#0 and #1).
  
  1.  In the second monitor I ran (LCD/VGA):
       $ sshfs cronos: ssh/cronos
  
       That is, mount my home at cronos into the directory ssh/cronos.
  
       In my main monitor (notebook/LVDS) a new Nautilus window was opened, 
       located at ssh/cronos.
  
  2. In the second monitor, same terminal I ran:
      $ cd ssh/cronos
  
  And then it crashs, showing a report window in the main screen.
  I'm confident when I try to access to the 'remote' directory it crashs. Because I tried several times.  I even used Nautilus to browse the 'remote' directory.  I wait for a while, etc.  But, I try to access from the second monitor, it crashed.
  
  It seems it is not possible to work with two monitors, if the sshfs was
  ran from the second one.
  
  
  If I run all the same commands only in the main window, it works fine. I mean, If apply the following procedure, it works:
  1.  In the main window:
       $ sshfs cronos: ssh/cronos
  
      In the same main window a new Nautilus window is opened (located at
  ssh/cronos).
  
  2. In the main monitor:
      $ cd ssh/cronos
      $ ls -las
  
      Everything runs smoothly.
  
  3. In the second monitor I ran:
      $ cd ssh/cronos
      $ ls -als
      ...
  
      And everything works fine also.
  
  
  As additional notes:
  - I'm using Hardy and it is up to date.
