Comment 5 for bug 253285

GODLiKE, I now have a couple more months of experience from looking at the user interface code than when I first answered this question. I believe the preview menu is not created until you go down to the headlines option. By hitting the left arrow key, I believe that you are attempting to access the menu before it even exists.

This issue is totally separate from your display problem of indexed content not displaying and crashing Entertainer. Can you check the trunk again to see if this is still a problem for you on Gentoo? If so, could you please file it in a new bug so we can capture the two different issues and track them separately.
