Description

Created attachment 6555 Show the fake mail icon with the SpiderOakONE menu

After upgrading from ubuntu 14.04 to ubuntu 15.10, the icon of SpiderOakONE on the indicator panel is missing. It has been replaced by a mail display icon. However, when I click on this new mail display icon, I can still launch SpiderOakONE. The new fake mail icon is not Thunderbird'one. The Thunderbird icon is present and working.
