Hello,
I'm using gnome-system-tools 3.0.0-9.1ubuntu1 on Ubuntu 22.04.2 LTS.
Steps to reproduce:
1. $ shares-admin
2. Click "Unlock"
3. Type password
4. Click "General Properties" tab
5. Click "Users" tab
6. SegFault!
Here's the backtrace:
```
Thread 1 "shares-admin" received signal SIGSEGV, Segmentation fault.
