Slack causes traybar icon errors

[carlpett]

Please fill out the following:

• Sway Version:

  • sway version 1.7 (Fedora 36)

• Description:
  Similar to Dropbox daemon errors under Sway #4185, I get this logged every time Slack changes tray icon (all read/unread channel/unread DM):

[ERROR] [swaybar/tray/item.c:127] :1.33768/org/ayatana/NotificationItem/Slack1 IconPixmap: No such property “IconPixmap”

Following the troubleshooting steps in that issue busctl gives this:

busctl --user get-property :1.33768 /org/ayatana/NotificationItem/Slack1 org.kde.StatusNotifierItem IconThemePath
s "/tmp/.org.chromium.Chromium.1WvC9C"

Introspection yields this:

In the IconThemePath directory there's actually an image Slack1_4.png, though. And it does appear to be drawn in the traybar. Is this simply logged before a successful fallback?
