banshee crash will interacting with lastfm

Binary package hint: banshee

When I tried to authenticate in my lasftfm acount banshee freeze (the window kind of fade in black). If I restart it it seems like I'm authenticated. I can use all the entry in the lastfm menu without problem but if a click on the "lastfm" line herself banshee freeze ( without the fade, It just stop responding but the music continue to play ) and then crash.

Here what I get from the console :
