I just wanted to answer an assignment and noticed that cyclic references kill Nautilus.
What I did
mkdir testFolder cd testFolder touch testFile.txt ln -s testFile.txt mySoftlink rm testFile.txt ln -s mySoftlink testFile.txt ls -l total 0 lrwxrwxrwx 1 moose moose 10 2013-01-20 21:20 myfile.txt -> mySoftLink lrwxrwxrwx 1 moose moose 10 2013-01-20 21:18 mySoftLink -> myfile.txt
Those two softlinks refer to each other. Now try to open this folder with Nautilus:
Nautilus opens and instantly closes again.
I use Ubuntu 10.04.4 LTS with Nautilus 2.30.1.
I know, the current version of Nautilus is 3.6.1, but how often do you find a bug which is so easy to reproduce?
The Nautilus Bugtracker is here, but where would you look for the bug?
