SDKLauncher-OSX crashes as well (I'm investigating). The Chrome extension and cloud reader seem to handle this EPUB fine.

@BluePick Should the link to this EPUB remain private? (is there any distribution copyright involved?) In the meantime, I have mangled the DropBox link you posted in this public issue tracker. Feel free to reinstate it if you feel that this ebook can indeed be shared publicly.

@BluePick your EPUB is missing crucial metadata (content.opf):

<meta property="rendition:layout">pre-paginated</meta>

and additionally:

<meta property="rendition:spread">auto</meta>
<meta property="rendition:orientation">auto</meta>

Furthermore, the SMIL durations are missing:

<meta property="media:duration" refines="#MANIFEST_ITEM_ID">0:00:00.000</meta>

I have now fixed the ReadiumSDK so that parsing of EPUB3 Media Overlays degrades gracefully in cases where the OPF duration metadata is missing or invalid (will push code to GitHub shortly).

However, you must explicitly specify that your EPUB is fixed layout (pre-paginated), otherwise it defaults to reflowable.

Regards, Dan

@danielweck Thank you so much

Regarding the "pre-paginated" missing metadata, I have filed a separate issue: https://github.com/readium/readium-sdk/issues/108 (not sure if readium-sdk should parse iBooks XML...to be determined)
