O Skype fecha sozinho!

[Maracampos]

Bom depois de chorar para resolver vim pedir ajudar!

Instalei o Skype tem dois dias, dai ele começou a fechar sozinho. Desistalei e instalei denovo.
Meu ubuntu é 11.10 de 32 bits.
Instalei baixando o pacote do site do Skype e por linha de comando. Jah dei sudo apt-get update e sudo apt-get upgrade.

Com update aparece isso:
W: GPG error: http://br.archive.ubuntu.com oneiric Release: The following signatures were invalid: BADSIG 40976EAF437D05B5 Ubuntu Archive Automatic Signing Key <ftpmaster@ubuntu.com>
W: Duplicate sources.list entry http://archive.canonical.com/ubuntu/ oneiric/partner i386 Packages (/var/lib/apt/lists/archive.canonical.com_ubuntu_dists_oneiric_partner_binary-i386_Packages)

Com upgrade tah ok.

Quando digito skype aparece isso:

(skype:7670): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
(skype:7670): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
