[13.04, 13.10, 14.04, 14.10] Nautilus crashed with SIGABRT in g_assertion_message() when trying to open file/folder's property dialog as root.

[Ｖ字龍(Vdragon)]

I tried to move a file(which is the lastpass installer tarball lplinux.tar.bz2 from http://lastpass.com ) from another user's home directory to mine download folder(Which as been converted to "~/下載" in Traditional Chinese), then tried to change its UID & GID to me...as root
UID changed successfully
When I clicked on the GID selection box...it hangs for a few second and crashed:(

To move further, I tried to open the property dialog of my home directory(/home/Vdragon)... crashed too.

It seems that any of file/directory belongs to me is affected. 100% reproducible.

Before nautilus crashed, a error window showes instantly(then vanished).
I tried to capture it as the attachment.

I suspect this issue is related to I used UTF-8 Chinese characters("林博仁") as my ... name
$ getent passwd Vdragon
Vdragon:x:1001:1001:林博仁,,,:/home/Vdragon:/bin/bash

then nautilus tried to grab my ...name for displaying UID, GID of my file/folder...then BANG

There will be no issue if I don't execute nautilus as root then see my file's properties.(however nautilus won't try to show the UID refers to who in this case)

Backtrace(since this is my first time doing this, please tell me if I missed something; ):

Title: nautilus crashed with SIGABRT in raise()
UpgradeStatus: No upgrade log present (probably fresh install)

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

[Mark Bennison (mark-bennison)]

I had a similar problem too. I was trying to browse to another users home folder to check disk usage. I launched a root nautilus through gksu nautilus. When I right clicked on the folder (in this case 'pictures') and selected properties I got the crash. Aport pointed me to this bug rather than reporting a new one, so I'm adding a little bit more information.

Firstly, the user in question is just a simple ASCII name ('betty') rather than from the extended character set (but, of course, it may not matter which part of the character set the characters come from). The dialogue as reported in the original bug appeared, but I wasn't trying to change the user and as I was running from a terminal it reported the following:

ERROR:nautilus-properties-window.c:1836:schedule_owner_change_timeout: assertion failed: (NAUTILUS_IS_FILE (file))

[PBS (pbs3141)]

Since my messages don't seem to be arriving at the Nautilus mailing list I'm posting the two patches here, at least so that they can be tested by other people.

[Ubuntu Foundations Team Bug Bot (crichton)]

The attachment "diff1.patch" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

[This is an automated message performed by a Launchpad user owned by ~brian-murray, for any issues please contact him.]

[PBS (pbs3141)]

The bug is still present in 13.10. Nautilus developers are not replying, so I'll post this updated fix for nautilus 3.8.2 here.

[PBS (pbs3141)]

Still present in 14.04 with nautilus 3.10.1. The patch above remains. It would be nice if this were fixed in the LTS release.

Reproducible in Ubuntu 14.10
