App crashes when trying to use UITableView

When launching my tab-based app, it crash when I'm trying to navigate to a tab with a UITableView in it, probably due to Interface Builder wrong connection I've made.

I have absolutely no idea why... I'm getting crazy over here!

I've simplified my code so now it contains 2 tabs;开发者_Go百科 when trying to navigate to the non-active tab, the app crashes with no further explanation.

I've posted the simplified source here: source download.

Any help will b appreciated.

Load the name of the UIViewController in tab. VideosGalleryViewController was not mentioned in the class. Check the screen shot attached.
