**Body:**

Hello Ubuntu Community,

I recently encountered an issue on my Ubuntu 24.04 system where the
`update-notifier` application crashed with the following error:

```
Sorry, Ubuntu 24.04 has experienced an internal error.
ExecutablePath: /usr/bin/update-notifier
Package: update-notifier 3.192.68build3
ProblemType: Crash
Title: update-notifier crashed with SIGSEGV in g_hash_table_lookup()
```

This error appears as a crash notification, and it seems to indicate a
segmentation fault (SIGSEGV) in the `g_hash_table_lookup()` function
used by `update-notifier`.

### System Details:
- **Ubuntu Version:** 24.04 (pre-release/experimental)
- **Architecture:** amd64
- **Package Version:** update-notifier 3.192.68build3

** Affects: update-notifier (Ubuntu)
     Importance: Undecided
         Status: New
