Bug#361091: locales fails to be installed - LANGUAGE vs LANG

[Joe Drew <drew@debian.org>]

Package: locales
Version: 2.3.6-5
Severity: serious

Setting up locales (2.3.6-5) ...
Generating locales (this might take a while)...
  en_CA.ISO-8859-1... done
  ja_JP.UTF-8... done
  ja_JP.EUC-JP... done
Generation complete.
*** update-locale: Error: LANGUAGE ("en_CA:en_US:en_GB:en") is not
compatible with LANG (en_CA)
dpkg: error processing locales (--configure):
subprocess post-installation script returned error exit status 9

I don't see why my LANGUAGE wouldn't be compatible with LANG in this
case...
