Gnome-tweak-tool dando erro no Ubuntu 12.04

[liebert_oliveira]

Olá,
instalei o Ubuntu 12.04 e estou usando a interface do Gnome 3. Está rodando sem problemas, exceto o gnome-tweak-tools que não abre.
Quando clico, antes dava uma mensagem de erro, agora não aparece mais nada. Quando tento abrir pelo terminal, ele mostra isso:

Meu notebook é um HP G42-350Br; 4Gb de ram; HD 500 Gb; processador Intel® Core™ i5 CPU M 460 @ 2.53GHz × 4; Ubuntu 12.04 (precise) 64-bit;
Kernel Linux 3.2.0-25-generic ; Gnome 3.4.1.
Já tinha utilizado o ubuntu 11.10 nesse mesmo note e o gnome rodava normal. Já tentei remover e reinstalar o gnome-shell, as extensões e o tweak-tools e deu na mesma.

Desinstale e reinstale-o pela central de programas do Ubuntu. Caso ocorra esse mesmo erro, é porque falta efetuar atualização do seu Ubuntu no gerenciador de atualizações.

[bawlaw]

nao adiante instalar e desinstalar..
esse é um bug conhecido do gerenciador de temas.. ja estão demorando pra concertar..

entre nesse site "https://extensions.gnome.org/extension/19/user-themes/" e desative o gerenciador de temas pelo site..
dai vai funcionar novamente
menos o gerenciador de temas, claro.

[liebert_oliveira]

Eu atualizei o Ubuntu e o tweak-tools ta funcionando agora, já tinha atualizado algumas vezes e não tinha dado certo. Só que mesmo assim algumas extensões estão com exclamação e não funcionam, tipo a do hidetopbar.

Não se preoculpe, no decorrer do uso e com as atualizações do gerenciador de programas do Ubuntu, se auto-atualiza, sem você se preocupar com esses detalhes.

ok.. valeu.
