Just to confirm, it did transfer OK.

Status changed to 'Confirmed' because the bug affects multiple users.

I copied a few files using Ctrl-C/Ctrl-V into my Ubuntu One folder on today's precise, and it's working fine. Can you reliably reproduce this every time? Which kind of file are you copying? (document type, size, etc.)

I would tend to say it happens whenever you try to copy from one device to another.

This happened here at least in these cases :
- from a smb share to local desktop
- from usb key to local desktop

Tested the other way around :

- from local folder (~/Images) to smb share
- from local folder to usb key

This triggers the bug each time here.

It occurs with any type of file and without copying to ubuntu one.

Yes, even in the same folder.

This bug applies for me too.

Even on copying files on some place on home folder nautilus crashes

Me too. Crashes on any copy and paste, any type of file from/to any location

--a little more info: Nautilus does not close until all of the files are done copying. So if I past several files, I can watch the progress bar until complete and then crash.

Moving something to the trash does not crash. Adding files from a different source, such as saving from FIrefox to a folder does not crash nautilus.

Hope that helps

When ever you try to copy something to the desktop folder will also trigger the bug.

Thank you for your bug report, I can't confirm that here, could somebody having the issue:
- install nautilus-dbg (and maybe the glib and gtk dbg as well)
- run "nautilus --quit"
- run "G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log nautilus"

trigger the issue

add valgrind.log to the bug report

Santa Joana D'Arc

File valgrind.log added.

I executed the same command again and trigger the issue.

File valgrind-2.log added.

Thanks, the logs don't have a lot of infos over the stacktrace though :-(

Could you try to reinstall the debs from the previous version:
https://launchpad.net/ubuntu/+source/nautilus/1:3.3.90-0ubuntu3/+build/3252050
or
https://launchpad.net/ubuntu/+source/nautilus/1:3.3.90-0ubuntu2/+build/3231502 (the previous one)

(should be basically downloading the lib and nautilus debs and dpkg -i those)

then restart nautilus (nautilus --quit; nautilus) and see if that's still an issue?

The duplicates here are all on amd64, I wonder if thats 64bits specific

The valgrind log also has quite some dbusmenu errors (set image) but that lib didn't change recently...

Comment #15 is interesting as well, is everyone here using nautilus-action?

@seb128: I am not using nautilus-actions, and seeing this crash too. 1:3.3.90-0ubuntu2 and 1:3.3.90-0ubuntu3 are working fine.

I tested the packages of 3.3.90-0ubuntu2 version and there is no issue
on copy and paste, even on removable devices.

That's a regression on version 3.3.90-0ubuntu4. On upgrading issue
comes back again.

There is no issue on copy and paste on the 3.3.90-0ubuntu3 version too.

It's likely a regression.

This crashes for me on every file operation. It's introduced by the zeitgeist patch, but I'm not entirely sure why just yet

Ok, I've disabled the zeitgeist patch for now. I don't really want to figure out what's going on on a Saturday evening :)

This bug was fixed in the package nautilus - 1:3.3.90-0ubuntu5

---------------
nautilus (1:3.3.90-0ubuntu5) precise; urgency=low

  * Disable the zeitgeist logging patch until we figure out why it causes
    nautilus to crash (LP: #944624)
    - update debian/patches/series

This is caused by stack corruption because the extra code in copy_job_done is sticking a pointer in to an int (which is why it works on 32-bit but not on 64-bit)

This bug was fixed in the package nautilus - 1:3.3.90-0ubuntu6

---------------
nautilus (1:3.3.90-0ubuntu6) precise; urgency=low

  * Fix LP: #944624 - Don't stick a pointer to an int, as it causes stack
    corruption on 64-bit architectures
    - update debian/patches/zg_activity_logging.patch
  * Turn on the zeitgeist logging patch again
    - update debian/patches/series

Hello everyone

This bug just ocurred with me. I have no idea how to fix it. Since I updated Ubuntu to 12.04 version, my netbook (asus eee pc 1005 HA) crashes constantly and randomly (sometimes when I am on the Internet or when I'm doing something on Libreoffice). As you might understand I'm being tired of this situation as I don't have a clue about this crash.

I would like to ask you if you have know how to fix this.

Thank you
