This could be a Windows-only bug; it's also failing for me with 1.6a1-1109, Win2K. Like bug 315600 and bug 297569, there's an exception thrown while parsing the feed, but this error occurs in a different spot.

I'm also seeing problems with feeds that contain spaces and newlines in their title tags (eg. all the blogs from CNET, like http://www.news.com/8300-13772_3-52.xml). This is with TB 2.0.0.14 (Windows). A folder is created, and correctly displays the headers and articles (so not the problem above), but the folder name contains spaces (ugly) and bug 291293 kicks in if you try to rename the folder (ie. you get duplicate folders afterwards). If I can't find a bug that mentions the malformed folder name, I'll create a new one and reference this.

fix in bug 547543.
