Disk Quota widget shows no content and has not icon in widgets explorer or in systray settings. Please see attached video for details.
when hovering the widget do you get any messages like "please install quota? if so then the quota package is not installed. Once installed I get the message "no quota restrictions found" as they have not be set.
Might that be a icon caching issue? Usually this should work (albeit the icon is still too large due to wrong margins).
Pending review request that addresses the empty space when no quota restrictions are found:
Still, the icon issue is still unsolved.

Disk Quota: display "No quota restrictions found." instead of an empty label
CHANGELOG: Disk Quota Applet: display "No quota restrictions found." instead of an empty label

If there is no quota, as said, the disk quota applet now tells you that no quota restrictions are found.
With respect to the missing icon: Let's track this in bug #363436. I will close this report therefore, since one part is fixed.
