我的 Vim：netrw 偶尔会挂起，大约每隔几个小时一次。症状：它不再响应Enter（打开文件、导航到目录）。它做响应其他 netrw 键如s和i。
我安装了一些插件，但（据我所知）没有一个会干扰 netrw。我不想vim -u NONE只是为了找到这个错误而开始使用。
顺便说一下，我也在 tmux 中使用 Vim，但我怀疑这是否与此有关。
我的问题是：
1 有人知道这个问题吗？
2 我如何调试 netrw 以便发现问题所在？
编辑以获取更多信息（回应@romainl 的评论）
我在本地使用 netrw。我的系统其余部分没有挂起，甚至其他分区中的 Vim 也没有挂起。
我正在使用的插件：
我在 Ubuntu 10.04 LTS 上，带有 Gnome（这是默认的吧？）Vim 版本：7.2.330
我不想使用，vim -u NONE因为问题很少发生，并且我不想在没有任何自定义设置的普通 Vim 中工作只是为了发现这个问题。
我的.vimrc：

当映射Enter停止工作，但 Vim 的其余部分保持响应时，看起来缓冲区本地 netrw 映射已被清除/覆盖。您可以通过以下方式调查映射的内容（包括它工作和停止工作时）
:verbose nmap <Enter>
