[Arch515]

Describe the bug

Having a desktop setup that causes libnotify_notification to fail to send a desktop notification will make sable freeze for a long time whenever it tries to show a notification.

Reproduction

1. be on kde plasma
2. remove the notifications icon from system tray
3. receive a notification in sable with desktop notifications turned on
4. it will freeze for a really long time

Expected behavior

It should fail silently or display some sort of warning instead of freezing.
