Nemo-preview crash when multiple GTK versions are installed

[roberts-code]

Hi,

nemo-preview crashes on Arch Linux + Cinnamon with three versions of GTK installed. Starting it from the console, it prints the error message:

Cjs-Message: 23:22:51.273: JS WARNING: [/usr/share/nemo-preview/js/viewers/audio.js 32]: Requiring Gtk but it has 3 versions available; use imports.gi.versions to pick one

I believe this is related to #437, where gst.js was fixed. When I also add imports.gi.versions.Gtk = '3.0'; to audio.js, nemo-preview works as expected.

Could someone familiar with the code base check, if this is the proper fix and add it?

Thanks, Robert

I'm also having this issue on the Cinnamon spin of Fedora 35.

I think I've fixed all places where this could occur, but I don't have anywhere to realistically test it on at the moment.

Let me know if someone can confirm it's fixed so I can close this. Thanks.

[roberts-code]

I just tested with commit ebe9cf2a7c0262eb638487938a78830d2b86d27c and can confirm, that nemo-preview works on Arch + multiple GTK versions. I see that it's in the main branch already, so this issue can be closed as fixed.

Thank!

What packages and versions do I need to check that has this fix applied? My nemo-preview still doesn't work.

Here's a list of nemo and cinnamon related packages on my system:

@raniesantos The fedora package works fine here.

[leigh@mpd lightdm]$ rpm -qa gtk{2,3,4} nemo-preview |sort
gtk2-2.24.33-8.fc36.x86_64
gtk3-3.24.34-1.fc36.x86_64
gtk4-4.6.4-1.fc36.x86_64
nemo-preview-5.2.0-3.fc36.x86_64

[ghost]

Interesting, mine says:

gtk2-2.24.33-8.fc36.i686
gtk2-2.24.33-8.fc36.x86_64
gtk3-3.24.34-1.fc36.i686
gtk3-3.24.34-1.fc36.x86_64
gtk4-4.6.5-1.fc36.x86_64
nemo-preview-5.2.0-3.fc36.x86_64

I have no idea why there are i686 versions in there.

And running it directly through the command line still gives me this:

Any ideas on potential fixes?

I tried these exact same commands in a virtual machine using GNOME Boxes.

• I downloaded Fedora-Cinnamon-Live-x86_64-36-1.5.iso and installed it in Boxes.
• I performed a sudo dnf update -y on the virtual machine.
• I took a random screenshot in the virtual machine, I ran rpm -qa gtk{2,3,4} nemo-preview |sort and nemo-preview ~/Pictures/Screenshot\ from\ 2022-06-06\ 23-54-17.png

This is what I got:

Ok sorry I took so long to get back.

I had to grab the rpms manually because I couldn't figure out how to force dnf to refresh the repo properly (I've only been using Fedora for 2 months).

It seems to have fixed it, the preview shows up now when I press space. If I try it in the terminal, it just spits out some text about mimetypes.
