Ubuntu 24.04: Simplenote 2.22.2 doesn't start

I have successfully installed Simplenote-linux-2.22.2-amd64.deb using dpkg.

### Expected

- If I type simplenote in a command prompt, I'd expect the program to start.
- If I type man simplenote, I'd expect the man page to be displayed
- If I type simplenote --help, I'd expect a usage information to be displyed.

### Observed

Trace/breakpoint trap (core dumped)

- If I type man simplenote, I get: No manual entry for simplenote

Reproduce the failure on Ubuntu 24.04 by installing Simplenote-linux-2.22.2-amd64.deb with dpkg and running simplenote, simplenote --help, and man simplenote. Trace the Linux packaging and launch behavior; done means the application starts, help displays usage information, and a Simplenote manual entry is available.
