Describe the bug
Ironbar segfaults when starting Mullvad VPN with the tray module enabled

To Reproduce
Steps to reproduce the behavior:

Start ironbar with the tray module
Start Mullvad VPN

Expected behavior
No crash

System information:

Distro: NixOS unstable
Compositor: Hyprland
Ironbar version: github.com/JakeStanger/ironbar@58190ab079

Additional context
Likely caused by one of the unsafe blocks involving cairo since the segfault mentions libcairo.so.2

@JakeStanger commented on GitHub (Aug 4, 2024):

Thanks for reporting. It sounds like Mullvad is helpfully providing an empty byte array for its image, rather than null, which is...helpful.

I've just pushed up a fix that adds a quick check that should help. Are you able to give that a quick test for me and see if that gets it please?
