Meu Vim: netrw trava com pouca freqüência, como uma vez a cada duas horas. Sintomas: ele não responde a Enter (abrir arquivo, navegar para um diretório). Ele faz responder as outras chaves netrw como s e i .
Eu tenho alguns plugins instalados, mas nenhum (eu sei) que interfere com o netrw. Eu não quero começar a usar vim -u NONE apenas para encontrar esse bug.
Eu também uso o Vim dentro do tmux, mas duvido que isso tenha algo a ver com isso.
Então, minhas perguntas são:
1 Alguém conhece esse problema?
2 Como posso depurar o netrw para descobrir onde está o problema?
Editar para mais informações (em resposta ao comentário de @romainl)
Estou usando o netrw localmente. O resto do meu sistema não está travado, nem mesmo o Vim em outras divisões.
Plugins que estou usando:
Estou no Ubuntu 10.04 LTS, com o Gnome (esse é o padrão certo?) Versão do Vim: 7.2.330
Eu não quero usar vim -u NONE porque o problema ocorre muito raramente e eu não quero trabalhar em um Vim sem qualquer configuração personalizada apenas para encontrar este problema.
