Comment 4 for bug 1245300

I have just encountered this too. Before discovering https://bugs.launchpad.net/ubuntu/+source/alacarte/+bug/1241841 I was having trouble getting a icon to appear for the application. I would delete and recreate the entry (accumulating hidden duplicates) with no success. I would then attempt to create my own entry from scratch, which would never show up. It turns out that the hidden entries were preventing the manually created one from being displayed.
