I'm not sure what happened, I've not changed anything since I've problem playing my MP3 songs with Banshee. Since then, I used Exaile, but a few days ago and until now, I tried to play the songs using Banshee and looks like it never crash the system anymore.
I guess the system updates have fixed the previous errors. Alhamdulillah, as there are many more options while using Banshee compare to Exaile. I like !
