Hi! Now it works as normal user (the one you attached) - didn't try as root yet.

The strange thing is that the first time I launched it, it didn't work ..unfortunatelly I didn't write the message down It was always a problem related to name, surname and alias.

Then I checked my address book and I saw that there was a duplication of some contacts..I adjusted them and then the program started working...

I hope it was useful..Now I'm gonna see how it works

PS: I don't have any particular Desktop enviroment .. I also thought it was a problem related to the theme I use but the problem arises also with the standard ones
