Pinta 2.1-1 problem opening images after update

[Radoslav Nenchovski]

Whether I right click on an image to open it or use the "Open" menu, I get these errors, one after the other:

System.UriFormatException: Invalid URI: The URI is empty.
   at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind, UriCreationOptions& creationOptions)

All of Pinta 2.1 deps are installed, including dotnet-runtime-7.0. The system is Arch Linux 6.1.3, if it matters.
I'll try downgrading Pinta for the time being cuz I use that program like a 100 times a day and I literally can't live without it.

Yup, downgrading to 2.0.2 fixes the problem.

Sounds somewhat similar to the stack trace from bug 2001734

I wasn't able to repro on my Manjaro VM, which should be similar to your arch linux package.
I suspect it might be something related to the settings file though - if you move ~/.config/Pinta/settings.xml elsewhere (don't delete this, in case the error is caused by something in this file!) to load with clean settings, does it still produce the same error?

[Radoslav Nenchovski (stalliondrift)]

It has nothing to do with the settings file, as this video demonstrates:

Thanks for the video!
I think it must be `PintaCore.RecentFiles.DefaultDialogDirectory.Uri.ToString()` that's causing the error then. The default dialog directory comes from `System.Environment.GetFolderPath (Environment.SpecialFolder.MyPictures)` which can return empty if the folder doesn't exist, so perhaps you e.g. don't have `XDG_PICTURES_DIR` defined

I'll add some more careful handling of failures here.

[Cameron White (cameronwhite91)]

I think this should be fixed by https://github.com/PintaProject/Pinta/commit/917fa5b908d72975c0063258e0cca2881daf36d9

If you could test out the fix, either by compiling from git or running the build from https://github.com/PintaProject/Pinta/actions/runs/3863584745 (requires GitHub login to download), that would be very helpful!
I'm not sure if the second error message that you got is a separate issue

[Radoslav Nenchovski (stalliondrift)]

I downloaded the source code from github and compiled it. Now in version 2.2 the problem is fixed, images open normally without errors.

[Cameron White (cameronwhite91)]

Great, thanks for confirming!
