The Kickoff launcher with an empty slot where the Bitcoin icon should be shown

In the favourite list, Kickoff doesn't show the Icon for Bitcoin-Qt's entry.
Clicking on the empty slot, that you can see in the in the attached screenshot,
launches the application as expected. It also shows the expected alternate text
on hover.

The icon is shown fine in the regular Kickoff menu structure and when searching
for Bitcoin in Kickoff. It's only missing in the favourite list.

I already removed and re-added Bitcoin from the favourites but this did not
change anything.
