The crash occurred when I attempted to copy a file from the UbuntuOne folder to the Documents folder after the latter opened.

[Rostislav Dzinko (rostislav-dzinko)]

It happens every time I visit one of "standard" forlder, I mean ("Pictures", "Document", etc.) in my home folder. Crashes started after last update.

[Felix Haller (felixhaller)]

same for me --> visit "standard" folders.

Reproduce it with: open home folder from launcher --> double click on "Pictures" or "Desktop" etc. --> nautilus window closes

[Roman Yepishev (rye)]

Created bug pattern for this bug as it is affecting many users.

[Ivan Calderon (neomasterx7)]

As a (bad) workaround, you can remove ubuntuone-client gnome temporarily until this bug is sorted out.
Note: i dont use the UbuntuOne service

sudo apt-get remove ubuntuone-client-gnome

After removing it nautilus no longer crashes while browsing common folders. (and browsing is a bit faster)

[Roman Yepishev (rye)]

Looks like this is related to LP 804946 which was supposedly fixed in libglib, however this looks like the same bug.

[Michael Kozma (myckeul)]

Nautilus crashed when i go on any subfolder of my home directory.

If i go on another folder all it's ok

[Michael Kozma (myckeul)]

Sorry, not any subfolder, just "Music", "Pictures", ...

[Luiz Augusto (luizaugustopc)]

The error happend whem I was trying acess documents folter through Dash

[10111 (joachim-neu)]

I have the same issue with all the folders in ~ except Video, Desktop, Ubuntu One and Dropbox.
Removing the package ubuntuone-client-gnome helps.

[Christer (christer-madsen)]

I was touble tapping to get into my Downloads folder (which I could see were syncing to Ubuntu One) when it Nautilus became black/white and crashed... Happened two times in a row now :/

[yohgaz (yohanngazziero)]

I'm affect to this bug. Nautilus crash when i click to Pictures, Documents or download

[Ratko (arheopterics)]

Confirmed.
@Ivan Calderon (neomasterx7)

 sudo apt-get remove ubuntuone-client-gnome

After removing it nautilus no longer crashes while browsing common folders. (and browsing is a bit faster)

[primefalcon (primefalcon)]

I wouldn't uninstall, prob won be too long until issue is fixed, just install dolphin or thunar until the issue is resolved

[primefalcon (primefalcon)]

Actually pcmanfm is a lot like nautilus but lighter and faster, so just use that until the issue with nautilus is fixed would be my recomendation

[Malte Pannemann (malte-pannemann)]

i just can open "examples", "Ubuntu One", "Videos". If i try to open any other folder natilus crashed.

[waspbr (notaduck)]

happened when I tried to open the ~/Documents folder.

[dFlyer (ggaribaldi)]

Seg faults anytime I try to open a sub folder under home.

[SpaceCowboy (majid-amman-latif)]

untarred vmware player 4.0.
after extracting prompt appeared asking to show files - i clicked yes
dialog with this error popped up

[xe2xpk (skorlowsky)]

Same here!...

(It happens every time I visit one of "standard" forlder, I mean ("Pictures", "Document", etc.) in my home folder. Crashes started after last update.)

[Rishikanta Pukhrambam (rishikantaet)]

Removing the ubuntuone-client-gnome package worked for me too.

[John Belton (jbelton1950)]

This is just to confirm the problem still exists, it only seems to affect the 64bit version on both my desktop and my laptop but not the 32bit version I have in Virtual Box under Windows XP on the desktop, that may be relevant.

[John Belton (jbelton1950)]

I was wrong it is now present on this version of Ubuntu11.10Beta2 32bit in Virtual Box in Windows Vista.

[Matheus Cavalcante (suetamac)]

Yeah, it affects me too. I was trying to access ~/Downloads

[jason (jasonrisenburg)]

I have a problem that I have a sever nautilus crash and I nolonger have a interface. I tried to report this but I have nothing but a wallpaper.

[Arif Munawwar Ahadi (hadinux)]

I have same problem, cant open home folder from launcher end then nautilus window it closes.
 I try this "sudo apt-get remove ubuntuone-client-gnome", After removing it nautilus no longer crashes while browsing home folders.

[Peter Ruibal (fmoo)]

All I did was run "nautilus &" from a terminal and wait a few seconds and it crashed pretty quickly

fwiw, I had both both ubuntuone-client-gnome package and nautilus-dropbox installed. I reinstalled both ubuntuone-client-gnome and nautilus-dropbox and things no longer crash
