我正在尝试跟踪在加载任何网页时出现在 sitecore 6.5 上的 NullReferenceException:

使该错误难以跟踪的有趣特征如下:
1) 我在 sitecore 日志中收到以下错误:
Exception: System.InvalidOperationException
Message: 'analytics' connection string is not defined
Source: Sitecore.Kernel
at Sitecore.Diagnostics.Assert.IsNotNull(Object value, String message)
at Sitecore.Diagnostics.Assert.ResultNotNull[T](T result, String message)
at Sitecore.Analytics.Data.DataAccess.DataAdapters.DataAdapterManager.ConnectionStrings.get_AnalyticsSettings()
at Sitecore.Analytics.Data.DataAccess.DataAdapters.DataAdapterManager.ConnectionStrings.get_Analytics()
at Sitecore.Analytics.Data.DataAccess.DataAdapters.Sql.SqlServer.SqlServerDataAdapterProvider..ctor()
然而,分析被很好地禁用:
<setting name="Analytics.DisableDatabase" value="true" />
...
<setting name="Analytics.Enabled" value="false" />
2)当我使用 Visual Studio 进行调试、附加到 IIS 并击中至少一个断点时,错误消失了(如果我没有击中任何断点,错误仍然存在)
3) 当我进行构建或触摸 web.config 时,错误再次出现。没有尝试重建,因为这会从网站/bin 中删除重要的站点核心 dll
关于我的环境的更多信息:visual studio 2010、IIS 7、sitecore 6.5、windows 7
您将如何跟踪此错误?
