JS error on the console:

Error: [Exception... "Component returned failure code: 0x80004005
(NS_ERROR_FAILURE) [nsIScriptableUnicodeConverter.ConvertToUnicode]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
chrome://messenger-newsblog/content/FeedItem.js :: anonymous :: line 308"  data: no]
Source File: chrome://messenger-newsblog/content/FeedItem.js
Line: 308

this feed must be confusing our unicode converter making it fail during conversion

the fix

I don't know what it is about some of the titles in this feed but they cause
our unicode converter that I added in a previous fix last week to throw an
exception.

The 'fix' is to add some exception handling code if we fail to convert the
string.

fixed. Heiko can you please  help us verify this in the 11/29 nightly 0.9 builds
when they come out? Time is short for 1.0 and we could use verification help.

If the windows builds are available I'll test if this error still occurs

I've successfully subscribes to that feed which caused this bug. So for me it
