[snap] Thunderbird does not support native notifications on KDE Plasma Desktop

[Erich Eickmeyer]

After testing and upgrading, I have discovered that the thunderbird snap does not support native notifications on KDE Plasma Desktop on either Kubuntu or Ubuntu Studio (same packages and desktop, really). This might be an issue with xdg-desktop-portal, so I'm also going to mark it as affected.

Thanks for the report, I reported a similar issue upstream a while ago (from using Thunderbird under xfce),

I've taken a bit of case to debug my xfce issue where I'm using notify-osd and it might be a different problem

What's the output of

$ gdbus call --session --dest org.freedesktop.Notifications --object-path /org/freedesktop/Notifications --method org.freedesktop.Notifications.GetCapabilities

in your environment?

In the notify-osd case it's missing the 'action' capability which was the problem but I expect that's probably not the case under KDE

could you also check the debug console in thunderbird and journal to see if there is any error?

I believe I'm experiencing the same bug. It's more egregious on Wayland because messages appear in the middle of the screen rather than at the designated edge.
It looks like this (email address intentionally blurred):

This seems relevant (from stdout or stderr when running thunderbird from terminal):
[Parent 180849, Main Thread] WARNING: Failed to connect to proxy: 'glib warning', file /build/thunderbird/parts/thunderbird/build/toolkit/xre/nsSigHandlers.cpp:167

(thunderbird:180849): libnotify-WARNING **: 16:34:31.333: Failed to connect to proxy

Status changed to 'Confirmed' because the bug affects multiple users.

For the record, I don't think this is relevant with this bug. Native Thunderbird and Flatpak have native notifications on KDE Plasma.

Hi Sebastien,

$ gdbus call --session --dest org.freedesktop.Notifications --object-path /org/freedesktop/Notifications --method org.freedesktop.Notifications.GetCapabilities

(['body', 'body-hyperlinks', 'body-markup', 'body-images', 'icon-static', 'actions', 'persistence',
'inline-reply', 'x-kde-urls', 'x-kde-origin-name', 'x-kde-display-appname', 'inhibitions'],)

And there was definitely something interesting in the debugger console:

mail.notification: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIAlertsService.showAlert]
    _showAlert resource:///modules/MailNotificationManager.jsm:359
    _fillAlertInfo resource:///modules/MailNotificationManager.jsm:219
MailNotificationManager.jsm:362:22
    _showAlert resource:///modules/MailNotificationManager.jsm:362
    _fillAlertInfo resource:///modules/MailNotificationManager.jsm:219

I hope that helps.
