Famitracker help menu segfaults on Kubuntu 22.04

[Expurple]

Hello, I've just discovered this software and decided to try it out on my Linux machine.

Steps to reproduce:

1. Download the AppImage of 9d16ed8 from here (it's only one commit behind the latest, which I'm too lazy to compile)
2. Run it
3. In the menu bar, click on Help -> About FamiTracker...

On my Kubuntu 22.04, the application segfaults and crashes. I'm too lazy to try this in a VM.

Stderr output:

EnableHtmlHelp
SUPPORT_TRANSLATIONS
Figure out 64-bit version of these asserts...
CControlBar::SetBarStyle
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
::WaitForStop()
::WaitForStop()
DSound::EnumerateDevices
RegisterSingleInstance
Segmentation fault (core dumped)

Segfault appears on click, the rest is printed on startup.

Backtrace in gdb (top 10 functions):

Please let me know if I should provide any additional info or if you aren't going to work on this. Maybe I'll attempt it myself if I feel like it.

I can reproduce on OSX so I may have some energy to put into this. Thanks for the report.
