Running gdb shows the program exited normally but the window is still open and i can crash it by visiting the folder

[Sebastien Bacher (seb128)]

that's because you tried to run it again while it was already running so it exited, you should attach gdb to the running one rather

[arjun (arjunak01)]

I'm getting a segmentation fault. but running "backtrace full" doesn't seem to end. i ran it for over half an hour,

May you please try to obtain a valgrind log following the instructions at https://wiki.ubuntu.com/Valgrind and attach the file to the bug report. This will greatly help us in tracking down your problem.

[arjun (arjunak01)]

I'm able to open the folder using dolphin without any issues

[Sebastien Bacher (seb128)]

the valgrind log has no error, did you stop the running nautilus when to run the new one? does gvfs-ls work correctly there?

[arjun (arjunak01)]

gvfs-ls works correctly. here is the log file,

[arjun (arjunak01)]

i have found the files that caused nautilus to crash. i've attached the files as an iso (compressing did not work) use ubuntu live cd and mount the image.

[aleandro (aleandrodasilva)]

in natty I have same bug

[Vasilis Mavroudis (vmavroudis)]

I also confirm the same bug in Lucid.

[Alexander Untch (untcha)]

I can confirm the same bug in Natty after installing the following package:
openmpi-bin

[Daniel Ejsing-Duun (zilvador)]

I had the same problem (dublicate bug https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/734212) and a source was found, but at that time nautilus did not crash anymore when entering /usr/bin even though the files are still there. This could be because of upgrading to Nautilus 3.2.0.

[Daniel Ejsing-Duun (zilvador)]

I was too fast. The some of the files had been changed and were no longer symlinks. I am sorry for the false alarm.

[Haitao Li (lht)]

The bug should have been fixed in upstream according to Nautilus developers mentioned in anther gnome bug report [1].

1. https://bugzilla.gnome.org/show_bug.cgi?id=607974

[Haitao Li (lht)]

I am still seeing the crash with Nautilus 3.2.1 on Oneiric.

Minimum steps to reproduce:
$ mkdir /tmp/dbg
$ cd /tmp/dbg
$ ln -s a b
$ ln -s b a
$ nautilus .
