"Binary package hint: nautilus

This is a very odd problem. I have 4 nfs shares mounted in /media (all are displayed on the desktop, and on the left side in nautilus) One of those 4 nfs shares makes nautilus crash. This was not a problem before when using Ubuntu 6.10. So 3 of them work fine, 1 makes nautilus crash when opening the nfs share.

Other comment from the bug submitter:

"I have found the reason for the crash, in the NFS share there was an invalid symlink. (a symlink that was pointing to something that wasn't there) When I moved the symlink into a subfolder it didn't crash, but when I open that folder with the invalid symlink nautilus crash again.

So this bug is totally unrelated to NFS, nautilus crash whenever you enter a folder with an invalid symlink."

I've experienced this bug myself. I'm running Nautilus 2.18.0.1, this does not happen with 2.14.3.

But it is easy to reproduce. Just make a symbolic link pointing to itself.
ln -s bla bla
Nautilus will crash when displaying the folder. I've had others confirming this.
