Dropbox icon present in other notifications in Loki

[zimmicz]

Hi, I've recently upgraded to Loki and elementary-dropbox works flawlessly except that the Dropbox icon is now present in some other notifications as well (especially in Slack).

I have same problem with WMail

Same for me (especially in Slack too).

Sorry for the delay. I have reviewed the issue and there seems to be a problem with elementary OS notifications.

When a notification with an unknown application name is fired, it seems that Gala tries to find an icon for it. I have not been able to reproduce this behavior in Ubuntu 16.04, so I think it is a Gala issue.

In Slack's case, the "org.freedesktop.Notifications.Notify" method is invoked with these arguments:

app_name       => string "Electron"
replaces_id    => uint32 0
app_icon       => string ""
summary        => string ""
body           => string ""
actions        => array [string "default", string "View"]
hints          => array []
expire_timeout => int32 -1

I am trying to understand why Dropbox icon is shown by default in this situation.
