drag & drop after update to debian 10

[Stefano Pardini]

Good morning everyone from Italy, I updated my system from 9 to 10 and I 
have a problem with drag & drop files, when I try to drag a file into a 
folder the file is not moved and an error message appears, I would like 
to know if someone is aware of a bug or has detected the same error, the 
system has been updated correctly via apt. Have a good day. Stefano.
