Ubuntu – Banshee isn’t starting anymore

my banshee doesn't start anymore. i tried to start it over the terminal just to see if something is broken but all the terminal gave me was this:

moere@SAMSUNG-NF110:~$ banshee

moere@SAMSUNG-NF110:~$ 

so i have no clue what to do. i already tried:

sudo apt-get purge banshee; sudo apt-get install banshee

and after that removing

~/.gconf/apps/banshee-1
~/.cache/banshee-1
~/.config/banshee-1

but nothing helped me out.
muinshee is working fine …

update: i tried using sudo banshee and it worked

`moere@SAMSUNG-NF110:~$ sudo banshee
