This is possibly related (or may the same as) #680968, based on the
backtrace.

** Description changed:

  Binary package hint: nautilus
  
  1) Ubuntu version: 10.10 (Desktop) 64-bit
  
  2) Package version: nautilus 1:2.32.0-0ubuntu1.3 (amd64)
  
  3) How to reproduce:
  - Create a SSH mount by using the File -> Connect to Server menu option.
  - Browse to a directory with files in the SSH mount.
- - Open a new tab in Nautilus. Browse to a local directory (i.e. 
/home/username). 
+ - Open a new tab in Nautilus. Browse to a local directory (i.e. 
/home/username).
  - Create a file in the local directory with the same name as any file found 
in the SSH mount.
  - Replace the file in the SSH mount with the newly created file (either by 
dragging or using keyboard shortcuts). Confirm the overwrite.
- - Switch to the tab containing the SSH mount. 
- - Press the "Up one directory" button. 
- - Nautilus crashes. 
+ - Switch to the tab containing the SSH mount.
+ - Press the "Up one directory" button.
+ - Nautilus crashes.
  
  4) What should happen: Nautilus should not crash and goes up one
  directory in the SSH mount.

libnautilus-ubuntuone.so)

+ 6) SSH server information:
  - Remote server runs Ubuntu 10.10 (Server) 32-bit.
  - openssh-server version 1:5.5p1-4ubuntu5

** Description changed:

  Binary package hint: nautilus
  
  1) Ubuntu version: 10.10 (Desktop) 64-bit
  
- 2) Package version: nautilus 1:2.32.0-0ubuntu1.3 (amd64)
+ 2) Package version:
+ - nautilus 1:2.32.0-0ubuntu1.3 (amd64)
+ - ubuntuone-client 1:4.6-0ubuntu2 (amd64)
  
  3) How to reproduce:
  - Create a SSH mount by using the File -> Connect to Server menu option.
  - Browse to a directory with files in the SSH mount.
  - Open a new tab in Nautilus. Browse to a local directory (i.e. 
/home/username).
  - Create a file in the local directory with the same name as any file found 
in the SSH mount.
  - Replace the file in the SSH mount with the newly created file (either by 
dragging or using keyboard shortcuts). Confirm the overwrite.
  - Switch to the tab containing the SSH mount.
  - Press the "Up one directory" button.
  - Nautilus crashes.
  
  4) What should happen: Nautilus should not crash and goes up one
  directory in the SSH mount.
  
  5) Full backtrace: (Edited - found debugging symbols)
  Program received signal SIGSEGV, Segmentation fault.
