Since Ubuntu 11.04 came out I have been using banshee since it is the default music player included in this distribution, however I have been having random crashes in Banshee at the middle of playback when the player finish a song (always a different song) it just crashes.

I ran it from the terminal to determine the reason of the crash and then came here trying to find a similar bug, it resembles this one: https://bugzilla.gnome.org/show_bug.cgi?id=638988 except for the type. This is the console output I got from the crashes:
