Startup Crash with Ubuntu 22.04

[Selebrator]

I tried running the (standard or self-contained) Linux version of the log manager on a minimal Ubuntu 22.04 install and get this fairly unhelpful stacktrace.

Unhandled exception. GLib.GException: Unrecognized image file format

   at Gdk.PixbufLoader.LoadFromStream(Stream input)

   at GW2Scratch.ArcdpsLogManager.Gtk.Program.Main()
Aborted (core dumped)

I made sure that libgdk-pixbuf (every package including that name) is installed. No idea why this isn't working. I don't need this to work. I just wanted to try this for #214.

I haven't seen this issue before... The program icon is the only icon that uses the ICO format, not sure if this is is caused by that, or if it's just because that's the first icon that is loaded. We could check platform when loading the icon and load a more suitable format on Linux if ICO needs some special format.

I have also found some recommendations online to refresh the mime database. Can you maybe try file --mime-type program_icon.ico on the file?

[Selebrator]

$ file --mime-type evtc/ArcdpsLogManager/Images/program_icon.ico
evtc/ArcdpsLogManager/Images/program_icon.ico: image/vnd.microsoft.icon

There is a file for that mime type:

$ cat /usr/share/mime/image/vnd.microsoft.icon.xml
<?xml version="1.0" encoding="utf-8"?>
<mime-type xmlns="http://www.freedesktop.org/standards/shared-mime-info" type="image/vnd.microsoft.icon">

Both outputs are the same for the Ubuntu where it's broken and the Arch where it's working.

Can you try running gdk-pixbuf-query-loaders --update-cache (possibly with sudo)? Just want to see if that fixes it or if the issue remains after that. It should be a part of the packages you said you installed: https://manpages.ubuntu.com/manpages/jammy/man1/gdk-pixbuf-query-loaders.1.html

After that please also try update-mime-database /usr/share/mime (that one almost surely needs sudo), and then the previous gdk command.

[Selebrator]

That program in not in my path, but I located it.

$ sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache
$ sudo update-mime-database /usr/share/mime

I ran everything twice to make sure that order does not matter.
This did not fix the issue.

[Sejsel]

Can you try running the first command one more time after the database update (if you didn't)?

If that doesn't work, I will try to take a look at it in a VM, but it might take me a few days. Thanks for the testing!

[Selebrator]

I alternated both commands a couple of times. Doesn't make a difference.

Take your time. I'm not in a rush. Actually I don't even depend in a fix. I got everything working like I want it to on my main pc.

[Selebrator]

The issue also effects my everyday Ubuntu 24.04 install. I don't use it for gaming, so I'm not bothered. Spent an hour trying to find a fix, no luck.

[Sejsel]

I just installed Ubuntu 24.04 in a VM, tried the self-contained latest version off gw2scratch.com and it worked out of the box for me. How did you install Ubuntu? Which version are you trying? Do you have the patch from #214 applied?
