Hello, I just installed kasvopus 1-2-2. I had the error everyone was having on this thread, but I solved adding the QtComponents repository.

I found it in the signature of another user in this forum (I can't recall his name now). The repo is the following:

Name: QtComponents
URL: http://dl.dropbox.com/u/41252806/maemo/
Distribution: fremantle
Components: oss non-oss source

Have fun! It works really well
