Timeshift GUI Crashes on Debian 12

[5p4r74cu5]

Describe the bug The Timeshift GUI crashes when opened on Debian 12, or hangs indefinitely in a terminal emulator until the process is manually killed.

To Reproduce Steps to reproduce the behavior:

1. Open Timeshift GUI via shortcut.

Expected behavior To open successfuly. I can use Timeshift via CLI, and have successful created a number of btrfs snapshots, I have not attempted to restore said snapshots yet, so cannot account for all of the CLI features working however.

Screenshots If applicable, add screenshots to help explain your problem.

System:

• Debian 12.2, 6.1.0-13-amd64
• KDE Plasma 5.27.5
• Timeshift 22.11.2-1
• I am happy to provide logs, however I don't know which log to fetch; here is a file list of my /var/log/timeshift directory:

UPDATE: I just ran sudo timeshift-gtk --debug in CLI to see if I could something helpful, but it actually successfully opened for the first time...

I got the shortcut working by installing pkexec, which timeshift-launcher was puking on in terminal without sudo. apt install policykit-1 Now when launching from the shortcut, a gui pops up for password for elevated privileges. I'm assuming that's how it's supposed to work.

I don't know what happened for me, but after restoring a snapshot it acts as expected...

[augmentedagent]

so the shortcut didn't work, so you ran it from CLI with sudo, took a snapshot(s), then restored a snapshot and now the shortcut works (for the first time)?

No, it launches normally from the applications menu in KDE like I remember it used to, prompts for password.. shrugs
