HTML tmLanguage causes crash

[matiaskorhonen]

The HTML tmLanguage file causes SyntaxKit to crash on "<h1 title='Hello Title'>Hello World!</h1>\n" .

My code:

let path = NSBundle.mainBundle().pathForResource("HTML", ofType: "tmLanguage")!
let plist = NSDictionary(contentsOfFile: path)! as [NSObject: AnyObject]
let html = Language(dictionary: plist)!
let parser = Parser(language: html)

let input = "<h1 title='Hello Title'>Hello World!</h1>\n"

parser.parse(input) { scope, range in
    print("\(scope) - \(range)")
}

I used the HTML plist from TextMate's html.tmbundle.

It managed to output:

meta.tag.block.any.html - (0,24)
punctuation.definition.tag.begin.html - (0,1)
entity.name.tag.block.any.html - (1,2)
punctuation.definition.tag.end.html - (23,1)

And then crashed with:

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)

The crash seems to be happening on line 103 of Parser.swift

Parsing worked fine when I tested SyntaxKit with the YAML plist included in the SyntaxKit fixtures.

This is on OS X 10.10.3 with Xcode 7 beta 2
