The backtrace produced using gdb to start the program, and then produce the bug

When changing songs in Rhythmbox (whether it is triggered by clicking the "next" button in the application or in the notification bar, or when the song playing is over), there might be possibility that it runs into a situation where it cannot find some songs in the library, with a "stop" mark in the first column of the song, and then jump to the next. After it happens several times, the contents on the UI are not redraw. Sometimes it is just the UI, and the songs are played normally. This situation can be temporarily resolved by double clicking another song to make the UI redraw and back to normal state. But the application would come to a completely halt, where the application does not respond, and there is no CPU usage (viewed from the system monitor).
