Edit button in Gradia Capture fails silently: empty stdin, then do_open() TypeError#382

Environment

  • Gradia 1.14.0 (Flathub, system install, up to date)
  • Gradia Capture: built from source at commit f70a212 (22 Aug 2026, latest master)
  • Fedora 44, GNOME 50.5, Wayland

Steps

  1. Take an area screenshot with the GNOME screenshot UI (Gradia Capture enabled)
  2. Click the pencil/edit button on the screenshot notification

Expected: Gradia opens with the screenshot.

Actual: Nothing visible happens. Gradia is D-Bus activated, fails to read the image from stdin, then the forwarded open call raises a TypeError in do_open(). The process exits ~10 s later without showing a window.

Opening a file directly works fine:
flatpak run be.alexandervanhee.gradia ~/Pictures/Screenshots/<file>.png

Log (journalctl --user -f -n 0 while clicking the button)

Two things stand out: stdin appears to be lost when the instance is D-Bus activated, and GradiaApp.do_open looks like it's missing a parameter for GApplication's open vfunc (files, n_files, hint).

    Thanks @orion82480 That confirms it's Gradia's D-Bus activation/open path rather than Gradia Capture. Affects any app launching Gradia with a file (Nautilus "Open With", the extension's edit button).

    It's possible this bug has surfaced because of Flathub's bump to "runtime-version": "51" - there is an associated PR already
