Hi,

Just to confirm this should be resolved for v4.1 due within the next or two.

RC5: RSS and get_UserAgent NullReferenceException

kleesman — Fri, 29 Jul 2005 10:05:41 GMT

After upgrading to RC5 I started getting the error below emailed to me. I've got an external web app that uses the rss feed to display the 3 most recent posts to a given forum. My app still works and when I click on the RSS link in the error message below, I still see the expected RSS comment, so it appears this exception is being handled gracefully. Looks like it might be looking for browser info when there isn't any to be had.
