The attachment will crash Firefox with a null pointer dereference if the Font Loading API is enabled (as it is currently on Nightly/Aurora).
This is because we're parsing the font descriptor values passing null for the sheet URI. The sheet URI gets stored in the URLValue, and then copied into the gfxFontFaceSrc object, where its operator== assumes that it is non-null.
