Account Details Fails To Open After User Picture Is Selected in Users and Groups

[Harry-W-Haines-III]

How to reproduce:

1. Do a an install to a hard drive and update everything (making sure all the latest changes are applied).

2. Go to System Settings.

3. Go to Users and Groups.

4. Click on the current account (notice while doing this, there a small segfault going on in the background).

Right after [COMMAND=/usr/share/cinnamon/cinnamon-settings-users/cinnamon-settings-users.py] in the syslog but not logged in System Reports | Crash Reports. Jul 07 15:56:15 powerbar systemd-coredump[4875]: [🡕] Process 4873 (w) of user 0 dumped core.

5. Change the account picture to something else from the black & white default.

6. In this case used chess pieces.

7. Close the window.

8. In a terminal window type "cinnamon-settings user"

9. Observe the Python error messages.

-- Could this be caused by something as simple as an apparmor issue?

My packages aren't fully updated. As of right now I do get a pause in step 4. But no crash when opening an user/account settings.

Looking at the cause of the pause, it appears to be caused by the w application (as your own log message suggested). The application calls w -sh $USER. It appears that w -s results now in a SIGSEGV.

This seems to be a known problem on the Ubuntu 24.04 base.

Having now updated my Mint22-Cinnamon system to the latest packages, repeating steps 1 through 8 does indeed cause the crash and errors you mentioned previously. So this issue is likely related to a recent update.

(I have a snapshot and can fetch my before/after package versions if and when requested.)

Sorry, forgot this wasn't the cinnamon repo.
