Gtk-WARNING **: Locale not supported by C library.

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Hi,

  I updated gcc-snapshot this morning, it updated locales, and then I
realize something went wrong. When I start a gtk app I get warning:

(process:5389): Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.

I thought I could just reconfigure locales:

$ sudo dpkg-reconfigure locales
[sudo] password for mathieu:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = (unset),
	LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by
another process: Resource temporarily unavailable


Does this rings a bell to anyone here ?

thanks,
