    使用的是archlinux，原来deepin music player用的好好的，突然不能运行了。输出如下：
    1. ** Message: pygobject_register_sinkfunc is deprecated (GstObject)
    2. INFO     Loading settings...
    3. INFO     Loading application theme...
    4. INFO     Loading MediaDB...
    5. INFO     Initialize Gui...
    6. Xlib.protocol.request.QueryExtension
    7. /usr/share/deepin-music/src/widget/lyrics.py:60: Warning: The property GtkWindow:allow-shrink is deprecated and shouldn't be used anymore. It will be removed in a future version.
    8.   self.set_property("allow-shrink", True)
    9. Error grabbing key 172, 0x1925120
    10. INFO     MMKeys mode: mmkeys
    11. Attempt to unlock mutex that was not locked
    12. 已放弃 (核心已转储)
    Copy the Code

    好像和pygtk有关的深度软件（深度音乐，深度终端，深度游戏中心）都遭殃了。因为是python所以不知道怎么debug，后来在网上查看了一下，是最新的glib2.42的问题...

    在glib2.42源码中glib/gthread-posix.c约1320行处：
    2. static void __attribute__((noinline))
    3. g_mutex_unlock_slowpath (GMutex *mutex,
    4.                          guint   prev)
    5. {
    6.   /* We seem to get better code for the uncontended case by splitting
    7.    * this out...
    8.    */
    9.   if G_UNLIKELY (prev == 0)
    10.     {
    11.       fprintf (stderr, "Attempt to unlock mutex that was not locked\n");
    12.       abort ();
    13.     }
    15.   syscall (__NR_futex, &mutex->i[0], (gsize) FUTEX_WAKE, (gsize) 1, NULL);
    16. }
    Copy the Code

    把abort();注释掉，重新编译glib，安装，深度音乐等就又可以正常运行了。

    建议楼主去给python报bug啦。
    我还没去过python的bug上报页面，哈哈
