osd-lyrics在audacious退出时崩溃

[Darren]

版本是:osdlyrics-0.2.20091010,audacious的版本是 2.2-beta1,不知道是不是osdlyrics的bug
我用Debian,因为dbus-glib的一个bug，在audacious退出时，osdlyrics也会崩溃,我于是打了
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=541632 中提供的patch。打过补丁
后
原来崩溃的位置不再崩溃了，但是在下面的地方还是崩溃了。

以下是backtrace:

很奇怪，destroy的时候MPRIS的地址变了，Banshee就没事。
目前暂时不知道问题出在哪里，先记录issue下来吧。
