I have this installation icon on my home screen but I have no idea why add I didn't try to install anything. This showed up after i ran out of battery and restarted after fully charging N9. Any ideas how to remove it? It says «Can't delete. Application does not exist». Thank you in advance.

[EDIT]
This is a temporary solution to manually delete these files:

If you have multiple useless icons, try this(with devel mode enabled):
-Open terminal and enter:
1. devel-su
2. dbus-monitor --monitor
3. Try to uninstall the offending icon and you can see it's name
from dbus-monitor output (control-c to exit)
4. Remove the offending .desktop-file from /usr/share/applications/.....

If your problem isn't solved at all, try if "autoremove" remove your phantom icons.
In terminal: apt-get autoremove

But problem returns for every single app I uninstall...
