Por que estou recebendo um erro ao tentar exportar uma lista de fluxo de trabalho para o Excel no CRM?

Question

Instalamos recentemente o Rollup 15 e, após a atualização, recebemos uma mensagem de erro quando tento exportar qualquer listagem de Fluxos de Trabalho para o Excel. No IE, recebo a mensagem genérica "Ocorreu um erro ...", mas eu retirei o arquivo abaixo de um arquivo de rastreamento:

MSCRM Error Report: 
Error: Exception of type 'System.Web.HttpUnhandledException' was thrown.   
Error Message: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Alguma idéia do que está acontecendo? Estou usando o CRM 4.0 - rollup 15, IE9, Win 7

Você viu o encadeamento nos Fóruns do Dynamics sobre esse problema link

Como primeiro passo, recomendo instalar o Rollup 18 (que é o mais recente rollup).
