I'm not sure what do you mean by “revision 300”. You can display the version of the relevant packages in console:

> rpm -qv nodejs-electron signal-desktop

Please also try running `signal-desktop` from console, try saving and attaching a file, and paste the log here.

I meant the revision listed under:

https://build.opensuse.org/package/show/network:im:signal/signal-desktop

> You can display the version of the relevant packages in console:
> rpm -qv nodejs-electron signal-desktop

| nodejs-electron-29.4.0-1.2.x86_64
| signal-desktop-7.9.0-1.1.x86_64

When I try to attach a file to a message, no message appears in the log.

When I try to save an attachment from a message, all that appears is:

| {"level":30,"time":"2024-05-22T14:18:17.878Z","msg":"MainSQL:

1.Do you have xdg-desktop-portal-kde installed? It is needed for proper support of file dialogs in Gtk-based apps in KDE.

2. Please run `electron https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file` and try to trigger the file input dialog from that page. (I'm trying to isolate whether this is a Signal problem vs Electron problem)

Yes:

| xdg-desktop-portal-kde-5.27.11-1.fc38.x86_64

The file selection dialog appears. However, when a file is selected and the selection is confirmed, "no file selected" remains. There doesn't seem to be any communication about which file was selected. This is also how “signal-desktop” behaves. The file dialog appears, but the selection does not lead to any action after confirmation.

Please download upstream electron binary from https://github.com/electron/electron/releases/download/v29.4.0/electron-v29.4.0-linux-x64.zip, unpack in some temporary directory and check whether the problem still appears.

If I run "./electron https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file" in the unpacked directory, it behaves identically. The file selection dialog appears, but the confirmation after the file selection leads to no result.

I ran the tests on a system with Fedora 39 and Gnome. Everything works there as expected. The problem seems to be limited to KDE.

Since the problem appears in upstream binaries, in is not specific to our Electron packaging. Please report it to the upstream bug tracker: https://github.com/electron/electron/issues/new/choose

You can ping me in the report (I'm @brjsp on github)

Thank you very much for your efforts.

I reported the error under "https://github.com/electron/electron/issues/42250".
