This could be two things. One, you may need to manually clear out the app manager cache. I don't have the URL of that thread handy.

I believe you might need to be root, delete the cache and then re-run app mgr.

If you had an N810 I might say the whole thing (including the issue with midnight commander) would be a symptom of this: http://www.internettablettalk.com/fo...ad.php?t=18043

but I believe that's only a problem for the n810's
