Wurdearring: 1 fan de 5 stjerren

After installing this add-on and restarting Thunderbird 17.0.7, Thunderbird's Add-ons Manager display of the installed extensions was missing most of the Add-ons' icons and descriptions! The buttons were missing their text until I moused-over each one.

Dizze beoardieling giet oer in eardere ferzje fan de add-on (1.3.1-signed.1-signed).
