刚装完bzr，却发现了下面的错误，真是讨厌啊。

bzr: warning: unsupported locale setting
  bzr could not set the application locale.
  Although this should be no problem for bzr itself,
  it might cause problems with some plugins.
  To investigate the issue, look at the output
  of the locale(1p) tool available on POSIX systems.

网上搜索了一圈，都没有靠谱的解决方案，当然也可能是大嘴牛搜索方法不当吧，还是本着老毛同志所说的”自力更生“的原则，大嘴牛自己看了一下，其实很简单，只要把bzr的setlocale改掉就可以了。diff如下：

 try:
-    locale.setlocale(locale.LC_ALL, '')
+    locale.setlocale(locale.LC_ALL)
 except locale.Error, e:
     sys.stderr.write('bzr: warning: %s\n'
                      '  bzr could not set the application locale.\n'

但问题大嘴牛看了lib下的locale.py文件，

    def setlocale(category, value=None):
        """ setlocale(integer,string=None) -> string.
            Activates/queries locale processing.
        """
        if value not in (None, '', 'C'):
            raise Error, '_locale emulation only supports "C" locale'
        return 'C'

看到直接传入空串应该也是可以的啊，怎么会出错呢，罢了，反正现在OK了。
