为什么选择SQL Schema Comparison的源会导致VS2012崩溃？

Question

看似没有理由,选择SQL> Schema Compare> New Schema Comparison然后尝试"选择源"会导致Visual Studio 2012崩溃.(它已按预期工作了几个月).

除了尝试重新安装之外还有任何可能的修复方法吗？

注意:尝试在另一个Visual Studio实例中调试崩溃会显示异常

试图按照这里发布的信息,我确实检查了正在访问的注册表项.删除发现的所有内容HKCU\Software\Microsoft\VisualStudio\11.0\SSDT\ConnectionMruList就可以了.
