使用WPF的ShowDialog打开表单时出现异常

Question

我有一个WPF应用程序,当尝试使用时打开一个表单ShowDialog(),我在下面的一台机器上得到了这个奇怪的例外.
知道问题可能是什么？

我遇到过同样的错误,问题出在Windows Presentation Foundation字体缓存服务上.它的缓存文件以某种方式被破坏.按照此MS知识库文章 http://support.microsoft.com/kb/937135中的说明,我能够解决问题.

这适用于3.0.0.0和4.0.0.0版本的Cache.

在我找到该文章之前,我刚刚停止并禁用了该服务,并且我的WPF应用程序正在启动.我怀疑禁用它会导致显示WPF应用程序的速度变慢(已经足够慢了),但是在现场有几台机器有这个问题之后,我禁用它并且从那时起就没有问题.
