@Martina - thanks very much for posting your feedback - the more the merrier please!

@crutledge - I can replicate that issue with loading that file, so it isn't just you. We shall take a look into it. I know one of the problem areas that remains in Sigil is the third party Xerces component which is used for xhtml validation (frankly it is dreadful, but a better long term replacement isn't part of this release). There must be something about the content in that file which is tripping this Sigil release up - we'll see if we can figure out the what and whether we can do anything about it...

Edit: If you remove that xml and DTD declaration from the file it will load. We will look further into it but that should keep you going in the meantime until we identify something better Sigil can do about it...
