Since I may be the only one having this issue, I'll assume it's a problem with my notification subsystem not passing a correct identifier along somewhere. I'll try using a different notification system. Regardless, I don't think the app should exit just because it got an invalid message identifier.

I'll continue to investigate.

[Simon-Laux]

just a guess: could be something in electron or libnotify, in that case it would be a bit out of our control. you could try a newer electron version. maybe it will be fixed there?

[Eszartek]

Debugging further using v1.34 appimage, clicking on a notification stoppped the app with the same console output:

[24059:1129/050435.287457:ERROR:libnotify_notification.cc(49)] notify_notification_close: domain=1236 code=36 message="GDBus.Error:org.freedesktop.Notifications.InvalidId: Invalid notification identifier"
Trace/breakpoint trap

So off to libnotify_notification.cc I go and see a reference to setting an ENV var ELECTRON_USE_UBUNTU_NOTIFIER. So I set ELECTRON_USE_UBUNTU_NOTIFIER=1 and run Deltachat, which now stays running when I click on a notification. It doesn't bring me to the message in Deltachat, or even bring Deltachat to focus, but this is better than having to restart Deltachat everytime I accidentally clicked the notification.

So the issue I have is Electron related (libnotify_notification.cc), not Deltachat code.

Finally, I figured it out! After reading about other Electron apps, like SIgnal that also crashed with notifications, one solution was tro install & run xfce4-notifyd. So I did it and now the DeltaChat notification bubble has a "View" button in it and it opens up the Deltachat window from the background right to the message.

[Eszartek]

In conclusion, I installed xfce4-notifyd and then added the line /usr/lib/xfce4/notifyd/xfce4-notifyd & to my .xinitrc , rebooted and notifications from DeltaChat work perfectly.

For those that run Artix or Arch Linux, this is the solution.
