Does it only crash on that specific image or other images as well?
Does it crash when you try to save a web page?
Do you see any errors when you run Opera from terminal?
What desktop environment do you use? GTK’s file chooser might need some schemas installed (e.g. by adding wrapGAppsHook dependency).

It also crashed when uploading an image, it was just that this was the shortest repro.

Fontconfig warning: "/etc/fonts/fonts.conf", line 146: blank doesn't take any effect anymore. please remove it from your fonts.conf

I use Plasma5.

Yup, you need to add wrapGAppsHook to Opera’s nativeBuildInputs. In the future, we may hard-code the schemas paths to libraries, which would allow us to drop the wrapper, but for now, it is necessary.

[coretemp]

@jtojnar I did what you said, but it just said that it was "not an ELF executable".

Opera currently has not nativeBuildInputs. I added an entry

nativeBuildInputs = [ wrapGAppsHook]

and added , wrapGAppsHook to e.g. line 5 of that file (something in the parameter list).

Can you try yourself? Or propose something that does work?

[jtojnar]

Adding wrapGAppsHook should be enough to get rid of “No GSettings schemas are installed on the system” error. Are you sure the error is the same after adding it and rebuilding?

[coretemp]

@jtojnar It does not build with what you described.

[coretemp]

@jtojnar I have a PR open for a bump to 56.X to show that I wanted to fix it. I think it would be best if you work based on top of that to try to make it work.

[coretemp]

@jtojnar I have added you to my repo, so you can do whatever you want to the feature/opera branch. Not sure whether you would use it or not.

[jtojnar]

I am not near my computer at the moment. What error does the build fail with? One thing I see that is wrong with the expression is that the installPhase is overridden without running the pre and post hooks.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.
