But the problem is also in the webpage. It is declared as XHTML (transitional) but is missing the closing of the <img> tag. Notice on lines before 137 all img tags are written as <img /> but the one at line 137 isn't.

So it depends on the mode TB is using to parse the webpage (if it is some strict standards compliance mode). Maybe it is more strict that even Firefox, that does not report the error.

From the error it looks TB uses the XML parser, which really can't accept this error. I don't know if this is intentional, or could be changed to match Firefox.

Imo this is invalid, the web page is in error, regardless of whether Fx is lenient in correcting for the XHTML.  And it's not specific to feeds; the same page opened in a content tab results in the same error.  Not sure what a good component is though.

understood the problem with the XHTML too, just think improving the fault tolerence will make TB better (and this is probably why Fx allows the page to be processed).
