Got a suspected bug and wanted to check with all of you before submitting. Having just installed IE7, my blog page stopped rendering (consistent with a PHP crash) when calling <?php bloginfo('rss2_url'); ?>. This is not a CSS issue, WordPress actually stops rendering the page and a partial page is returned from the server.
I don't see this problem when accessing the page using Firefox.
The workaround is to use bloginfo('rss_url') instead which does not manifest the problem.
Have anybody seen of this? If not, I'll submit as a bug.
