It's reproduceable for me. However, it's not the icon that's not transparent (the icon is, at /usr/share/icons/hicolor/16x16/apps /updates-notifier.png); it's the widget that it's on. Note also that the problem isn't update-manager, it's update-notifier, so we're attached to the wrong package here.
