I added a couple of debugging lines in u-c-c-signon, and here's the result:
========== unity-control-center -v credentials -- application=shotwell (unity-control-center:27615): credentials-cc-panel-DEBUG: Loaded (unity-control-center:27615): Gtk-DEBUG: Connecting to session manager ** (unity-control-center:27615): DEBUG: Enabling debugging ** (unity-control-center:27615): DEBUG: Extra argument: application=shotwell (unity-control-center:27615): credentials-cc-panel-DEBUG: cc-credentials-preferences.vala:107: no params credentials-cc-panel-Message: cc-credentials-accounts-model.vala:259: Error loading icon 'vimeo': Icon 'vimeo' not present in theme credentials-cc-panel-Message: cc-credentials-providers-model.vala:109: No desktop app info found for application name: com.ubuntu.developer.webapps.webapp-facebook_webapp-facebook credentials-cc-panel-Message: cc-credentials-providers-model.vala:109: No desktop app info found for application name: uoa-integration-tests credentials-cc-panel-Message: cc-credentials-providers-model.vala:109: No desktop app info found for application name: com.ubuntu.developer.knitzsche.oa-2_oa-2 credentials-cc-panel-Message: cc-credentials-providers-model.vala:109: No desktop app info found for application name: it.mardy.account-tester_account-tester credentials-cc-panel-Message: cc-credentials-providers-model.vala:109: No desktop app info found for application name: com.ubuntu.reminders_reminders (unity-control-center:27615): credentials-cc-panel-DEBUG: cc-credentials-account-details-page.vala:239: No configuration widget for provider windows-live (unity-control-center:27615): credentials-cc-panel-DEBUG: Startup argument given: application=shotwell ========== It looks like our plugin is "constructed" and *then* the "argv" property is set. Our code assumes that this is a construct property. I'm not sure whether this assumption is correct, but since this used to work, it's very likely that something changed in u-c-c. ** Also affects: gnome-control-center-signon Importance: Undecided Status: New ** Also affects: unity-control-center (Ubuntu) Importance: Undecided Status: New ** Changed in: gnome-control-center-signon Status: New => Confirmed ** Changed in: gnome-control-center-signon (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1334231 Title: Starting with application=... doesn't seem to be working To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center-signon/+bug/1334231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
