Segfault due to wl_output listener function being NULL

[Jackaed]

General description of bug:

Whenever I run fastfetch (default config), it gets as far as printing out my packages before it segfaults and throws the following error:

listener function for opcode 4 of wl_output is NULL

Often helpful questions:

• Does the issue occur across multiple terminal emulators? Y
• Does the issue occur across multiple shells? (bash, zsh, fish, etc) Y

Output of fastfetch --version:

Note that I've installed it via the .deb package, which was seemingly a fix for the same issue under #188.

[Jackaed]

I uninstalled it and tried installing via pacstall, and it is now working correctly, I probably had a missing dependency. Thank you for replying so quickly earlier!

[Jackaed]

When I install via Pacstall, it doesn't seem to detect my imagemagick installs, and generally recognises far fewer dependencies than the deb version. Looking through the dependency list, I seem to have all of the non-optional dependencies on my system installed, so I'm still not sure as to why this is happening.

Any ideas? I would quite like imagemagick working if possible!

[Jackaed]

Note the behaviour is now different, it seems to work properly with --load-config devinfo for some reason, but doesn't work correctly without it or when using devinfo-verbose.

[Jackaed]

Okay, installing libmagick from source and then building fastfetch from pacstall seems to have worked. Not sure what's going on with the .deb build, but glad I got it working in the end.
