Still reproduces on Ubuntu 24.04 (noble), xdg-utils 1.1.3-4.1ubuntu3, GNOME.
Any `xdg-settings set default-url-scheme-handler <scheme> <app>.desktop` also sets `text/html` to that app. Reproduced on 2026-10-09: registering `grokbot://` for `grok-bot.desktop` changed `text/html` from `firefox_firefox.desktop` to `grok-bot.desktop`. Electron apps hit this the same way Telegram did in the original report. Upstream fixed this in xdg-utils 1.2.0 on 2023-08-09 (Joe Mou, "Fix set_url_scheme_handler_gnome3 to not associate text/html handler"). The 1.2.1 script drops the no-argument `set_browser_mime "$2"` call and checks `get_browser_mime "$MIME"`. Debian and Ubuntu 25.10/26.04 already ship 1.2.1. Please backport that fix to noble. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921497 Title: xdg-settings set default-url-scheme-handler changes the entry for mime type text/html To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xdg-utils/+bug/1921497/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
