Nautilus keeps opening when ubuntu one plugin is installed

[Thomas Goossens]

Hi

I use ubuntu 10.10 with all the latest updates.

Yesterday a strange problem arised: when i log on, after a while nautilus starts opening and keeps opening in an endless "loop"

Here you can see my problem:
http://www.youtube.com/watch?v=wlkq_4WZl8g

Hope you can find what the problem is, if you need any additional information please ask me

Thanks in advance and good luck.

[Thomas Goossens (a-contact-thomasgoossens-be)]

Hi

I could stop the loop by entering these command (in this order)

---
killall -v nautilus
pkill nautilus
pkill nautilus
----

i know this seems strange but it stopped and killed all the opened natuilus screens after i did pkill twice

now when i want to start 'nautilus' in terminal i get the following error:

----
thomas@thomas-ubuntu:~$ nautilus
Initializing nautilus-gdu extension
Segmentation fault
---

The only way to run nautilus is 'sudo nautilus' and then it works

I cannot use acces my files any more via nautilus (the 'normal way') until i reboot

Hope this helps!

[Fabio Marconi (fabiomarconi)]

Have you tried to reinstall nautilus:
sudo apt-get clean
then reinstall nautilus using synaptic
Fabio

[Thomas Goossens (a-contact-thomasgoossens-be)]

I just tried it
and it didn't work, the problem is still there

[Thomas Goossens (a-contact-thomasgoossens-be)]

After some research I uninstalled ubuntu one and this fixed the problem.

[Thomas Goossens (a-contact-thomasgoossens-be)]

I have reinstalled ubuntu one, and for now no problems have arised.

If you want the exact error i found in the log file:

 [ 553.888980] nautilus[3939]: segfault at 0 ip 00d186f7 sp bff4e894 error 4 in libglib-2.0.so.0.2600.0[cb7000+cd000]

Hope this helps!

[Sebastien Bacher (seb128)]

if uninstalling ubuntuone fixes the issue the bug is probably there

[Natalia Bidart (nataliabidart)]

I just confirmed this bug. To reproduce, I can do the following:

* be sure ubuntu one is running
* plug a few USD storage devices
* tons of nautilus processes will be started and the window list will go crazy, though no window will actually pop out
* I never get to access the just mounted usd devices

What version of ubuntuone-client-gnome do you have installed? I don't see it listed anywhere.

[Thomas Goossens (a-contact-thomasgoossens-be)]

When I install ubuntuone-client-gnome 1.4.4.1-0ubuntu1 (maverick) the problem appears

[Natalia Bidart (nataliabidart)]

nessita@dali:~$ aptitude show ubuntuone-client-gnome
Package: ubuntuone-client-gnome
State: installed
Automatically installed: no
Version: 1.4.99+r745~maverick1

[dobey (dobey)]

OK, I am unable to reproduce the problem with the version that Naty seemed to do so with (and I'm running 11.04 already, so not sure if something different in nautilus or some other lib might have 'fixed' it inadvertently); and Naty tells me she can't reproduce with the stock version from 10.10 main.

Thomas, if you are still able to reproduce the problem, would you mind trying to get a backtrace to use? You will need to perform these steps to do so, in a terminal (Programs->Accessories->Terminal):

gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop False
sudo apt-get install ubuntuone-client-gnome
gdb nautilus

Then, all of the following will be done in gdb (as show with the (gdb) prompt prefix:

(gdb) run

reproduce the crash in nautilus, and come back to the terminal where you ran gdb nautilus from:

(gdb) thread apply all bt

Copy and paste the entire output from that point, into a new comment on this bug. You can then use the "quit" command inside gdb, and run the following in the terminal, to restore your previous setup before the debugging session:

sudo apt-get remove --purge ubuntuone-client-gnome
gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop True

Thanks.

Actually, I will be reinstalling this particular system to perform a
very specific function. I will no longer be able to troubleshoot the
issue. My VM does not appear to exhibit this particular behavior...

Rodney this system is still viable. I decided to leave it be and just
add disk space. I now access X remotely and not locally from this
system. Not sure if this will make it more difficult to troubleshoot.

For me, the nautilus crashes only happen when ubuntu one file sync is enabled. I can enable notes, contacts, and broadcast messages with no problem

Notes
* I am available to do more debug if given some direction.
* I have 2 machines both with ubuntu 10.04. One exhibits the problem, one (fresher install) does not.
* I'm using deb http://ppa.launchpad.net/ubuntuone/stable/ubuntu lucid main

Same problem here (actually in an openbox desktop)

If I first run ubuntuone-launch the nautilus, I get the following:

jeff@jeff:~$ nautilus --no-desktop

[Africanus (africanus)]

Same problem in Italy:
http://forum.ubuntu-it.org/index.php?topic=430439.0

An interesting solution, he removed nautilus and now his system works

I forgot to say above that I am running 64 bit.

[Africanus (africanus)]

I solved or worked around the problem using this link:

https://wiki.ubuntu.com/UbuntuOne/Bugs

this section:

ROOT_MISMATCH in syncdaemon.log - This normally indicates that there may be two Ubuntu One accounts, one in the local cache and another setup in the keyring. This happens if the user installed Ubuntu One with one account and then sets up the computer again with a different account (but all the old Ubuntu One files in ~/.local/share/ubuntuone are still there under the old account). Working around this:

Open Applications->Accessories->Terminal and run:

  u1sdtool -q; killall ubuntuone-login ubuntuone-preferences;
  sudo rm -rf ~/.local/share/ubuntuone
  rm -rf ~/.cache/ubuntuone
  rm -rf ~/.config/ubuntuone
  mv ~/Ubuntu\ One/ ~/Ubuntu\ One_old/
Open Applications->Accessories->Passwords and Encryption Keys, go to the Passwords tab, delete the Ubuntu One and Desktopcouch tokens by right-clicking on them and selecting "Delete"

Back in a terminal session, run:
  u1sdtool -q; killall ubuntuone-login; u1sdtool -c

[dum (dummyxl)]

about 3 weeks ago a had the same problem after updating the system and reboot. That time i did a full reinstall.
Nu this morning the same thing happens again! this time I had no login (gdm) screen. so i rebooted to save mode, fix the X server to default. and restarted X.
That did give me back GDM and I was back on the desktop. But the same error appears now a loop of nautilus windows inside the taskbar and nautilus will not open and no desktop icons. the cursor was always busy on the desktop.

This error is the same as the first time only not the GDM part the first time.
So this is not a configuration fault I was thinking...

but i solved the problem (for now) I downloaded the ATI drivers from the website and opened a terminal.
I cd to the directory (my case cd /ralph/Bureaublad) and did sh ati<tab> and enter.
this installs the new ati driver again, and half way the setup nautilus loop was gone and after a reboot everything is back to normal again.

sorry for maybe some bad English.

maybe my story will help someone here to solve the problem, i think this is the same bug (but for me noting to do with Ubuntu one, at least i think i is not)

[dum (dummyxl)]

I forgot to mention above:
I'm running Ubuntu 10.10 32bit and all updates

[Emil Gitman (ediulia)]

I running 11.04 after upgrade from 10.10 with all updates.
 Have the same problem with nautilus. It's looks like desktop hangs at the beginning. But problem is nautilus hang. You can just kill nautilus onse and continue to work. Even with ubuntu one. Until next boot.
