Terminal output of a run of `gdb neochat`.
SUMMARY
When trying to enter the settings category "Security" or "Device", NeoChat
crashes with a segmentation fault.
STEPS TO REPRODUCE
1. Install NeoChat, version 24.08.2, from my distribution (Artix GNU/Linux;
https://packages.artixlinux.org/packages/world/x86_64/neochat/)
2. Start `neochat`
3. Enter login credentials
4. Open settings -> Security
5. Observe that NeoChat crashes with a segmentation fault
OBSERVED RESULT
Crashes with segmentation fault.
Here I copypaste a gdb backtrace; the full gdb session terminal output (which
includes NeoChat's terminal output) I attach.
```
