系统： Ubuntu OpenERP GTK client
动作： 每个Tree view 中， 打印->Print Screen时出错！
上下文：全新套帐，已安装base_report_cn模块
自诊：好像locale.nl_langinfo(locale.D_FMT)取得的date字段为空了，而要求不为空
无效尝试：1. 更改、删除当前user的时区
                2. 更换用户
                3. 更改用户的语言
解决：ps_list.py中：
      注释掉这行：  #_append_node('date', time.strftime(str(locale.nl_langinfo(locale.D_FMT).replace('%y', '%Y'))))
        把这行的注释去掉： _append_node('date', time.strftime('%d/%m/%Y'))

请求： 怎么回事 ?

我隐约觉得这个问题有一定的普遍意义，所以即使我使用笨拙的办法把它解决了，但是还希望哪位仔细分析下，所以就把它提了出来。
