This program is caused by programs that send notifications with a null summary.
I have fixed this bug in Geary and have done some research around this problem [1]: > Giving a quick look to https://developer.gnome.org/notification-spec/ it > seems that 'body' is optional and may not be supported by all notification > servers (Table 1. Notification Components, Table 5. Server Capabilities). > 'summary' seems to be required, although I couldn't find any explicit > sentence saying so. So the problem seems to be arised by applications that do not follow the specification. However it's worth noting that Notify-OSD could be smarter and show the body of the notification even if no summary has been set.
