Hi @advocatux ,
I have tried the command proposed and works successfully.
Thanks for your answer.

I have solved the issue. The fail was a media scanner corrupted database located in:
/home/username/.cache/mediascanner-2.0/mediastore.db
Once removed the file and rebooted the phone, new database was created succesfully.
I left this topic because may be useful to other users with the same problem.
Thanks to all the developers for keeping this project alive
