SSH into your iDevice and browse to /Applications/Cydia/ and create two copies of package.js computer ( one is your backup and you will edit the other one ) .
Inside that file search for
var depiction = package.depiction
. Edit that line so that
depiction = package.depiction
will become
depiction = null
Now save the file and copy it back to /Applications/Cydia/ , overwriting the original one. Thats it. Now restart Cydia and enjoy.
