Quod Libet parou de iniciar.
« Online: 18 de Julho de 2010, 04:23 »
Olá,

Utilizo o Quod Libet como player de música principal, pois gosto muito da sua organização de biblioeca e a forma que posso customizar as janelas com as informações que eu quero, enfim, mas agora tenho um prolblema, após o notebook ter reiniciado por ter acabado a bateria eu não consegui mais fazer o Quod Libet funcionar, clico no ícone, acontece a animação mas ele não inicia.
Já tentei instalar e desinstalar, desinstalar, reiniciar, instalar e afins.

É isso, espero que possam me ajudar.
Abraços.

Alguém sabe se posso limpar os registros dele e só dele?
O que sobra quando eu desinstalo ele? Alguma coisa que dá para remover manualmente?
Será que o 'erro' continua em algum arquivo que não some com a desinstalação?

Abraços.

Acho que tive um avanço, descobri que o problema era no arquivo '_library.sy' que encontra-se no caminho "/usr/lib/pymodules/python2.6/quodlibet/library/".
Deletei esse arquivo, desinstalei tudo, removi tudo do quodlibet, e mesmo assim ele não funciona pois aparece que não possui o arquivo library.sy.
Vou colocar aqui o erro que aparece no terminal e depois coloco o que está escrito dentro do arquivo library que dá erro.

Erro no terminal:

Alguém usa o QuodLibet?
Se sim, tem como mandar o arquivo "_library.py" que encontra-se na pasta "/usr/lib/pymodules/python2.6/quodlibet/library".

Agradeço.
Abraços.
