Chromium 调用 _exit(1)。不会生成核心文件

从星期五开始，我在启动 Chromium 时遇到了麻烦。我已经使用这台笔记本电脑（联想 Thinkpad T540p）和 Ubuntu 14.04 32 位大约 3 年，并且一直使用 Chromium。但是，当我单击 Unity 栏中的图标时，图标开始闪烁，就像它即将启动一样，但没有任何反应。没有错误代码，没有窗口，什么都没有。我尝试从终端启动它chromium-browser并得到以下错误跟踪文件：

我检查了我是否对铬进行了任何更新，但我唯一能找到的是它停止工作前两天的情况：

我曾尝试从软件中心重新安装 Chromium，但这无济于事。似乎我不是唯一一个有问题的人（例如ubuntuforum 上的这个帖子），但我还没有找到解决方案。
