Comment 0 for bug 768738

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).
- 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: (I couldn't find debugging symbols for libnautilus-ubuntuone.so)
Program received signal SIGSEGV, Segmentation fault.
