Incompatible applications nokia store
 

Hi, these days i've been experiencing an issue.
When i try to install something from the store, i get http://i.imgur.com/YAkbMck.png
and removing something from the home screen i get this

(don't know if it's related or not)
even sending SIGTERM and/or SIGKILL to pkgmgrd i'm not able to remove anything.
installing/removing/purging using dpkg as root (devel-su and opensh, on open mode) works fine
can anyone help?

EDIT

fixed it. basically i had installed a version of 'calligrameego' older than the system one
