Python Web2py:运行时出现内部错误

我得到这个错误

已发出内部错误通知单：不可恢复

尝试从运行web2py时

我正在使用Ubuntu12.04，并且已经有了Web2Py1.99.4。但我想检查一下新版本。正如repo的自述文件中所述，我应该只运行pythonweb2py.py

但是，当我启动服务器时，我发现了内部错误

下面是我从shell中得到的信息：

那么，这里出了什么问题？

提交刚刚中断。如果查看代码，dbs变量永远不会被定义，因此close_all_instances函数总是会失败。有一个关于它的错误报告：

你可以在自己上面应用补丁，或者使用我的分支，我已经应用了补丁并发送了一个请求，或者你可以在代码被破坏之前使用提交，或者只是等待它在master中得到修复，我认为这很快就会发生。
