Description Neville A. Cross 2019-01-15 14:53:11 UTC
Created attachment 1520784 [details]
screen capture of the home directory

Description of problem:
When I login in Fedora 29 with Mate official spin a random folder is created at home directory with a invalid encoding.

Version-Release number of selected component (if applicable):
lightdm-1.28.0-2.fc29.x86_64
mate-desktop-1.20.4-1.fc29.x86_64
kernel-4.19.13-300.fc29.x86_64

How reproducible:
Every time I log in at the desktop there is a new folder with invalid encoding.

Steps to Reproduce:
1. power on computer
2. log in at desktop environment 
3. open caja to look at home contends or open terminal to do ls

Actual results:
There is a new folder with invalid character encoding

Expected results:
There should not be any new folder

Additional info:
I tried using inotify from console (Ctrl+Alt+F2), then went back to DE, made a login and went back to console. There was inotify event reporting the folder creation.
I tried with auditctl, but was unable to make a rule that catches the folder creation. I found out that the time on authentication in lightdm reported on auditctl is the sale as the time reported by ls at the terminal.

lightdm itself is very unlikely to be the cause here. More likely is something that runs near the beginning of your login session.  One possibility is anything in 
/etc/xdg/autostart/
or
/etc/X11/xinit/xinitrc.d/

Hi,

I see the exact same problem on several Fedora machines. These run GDM with Gnome/Mate/XFCE/Openbox, so it's not related to lightdm.

The machines that show this problem have one thing in common: they were upgraded from Fedora 28 to 29. The problem also occurs with new user accounts. I have two other machines with fresh Fedora 29 installs that do not show this behaviour.

Comment 3 Neville A. Cross 2019-01-16 03:50:52 UTC
A friend toldme that he use gdm and saw one folder like that in his machine, but only once. My home computer has a fresh install of Fedora 29 from Mate Spin. I just got the same behavior in my work computer, also fresh install of Fedora 29 from Mate Spin. Looking at the dates of the first random folder, it did not happen until late December at my home computer and January on my work computer. I wonder if it is something broken with an update. Can anybody help me to trace which program is creating this random folder. I am willingly to get a second look at the auditctl tool or other tool to find why this is happening. At least, at the moment it is consistent and maybe I can find the source.

Comment 4 kaasboer 2019-01-16 06:48:52 UTC
Good morning,

EDIT: the problem seems to be solved with a new abrt-update (see below).


@Neville: thank you for the hint to use auditctl here:

# auditctl -D
# auditctl -w /home/kaasboer/ -k kaasboer_home

..looged in as user...

# ausearch -k kaasboer_home | aureport -f -i > xxx
# auditctl -D


The result is, that obviously "abrt-applet" is the culprit:

37509. 16.01.2019 07:09:41 0�\��U mkdir yes /usr/bin/abrt-applet kaasboer 60695

Taking a look at my logfiles:

# grep abrt /var/log/dnf.rpm*

...finds updates of abrt-related packages installed a few days ago.

And just as I'm writing this there comes another set of updates for abrt-packages.

After installing these the problem is gone so I think this ticket can be closed.

cu,
kaasboer

I just updated my home computer. Only updated abrt related packages. There are no more random folders. Thanks.
