This thread was notorious for having false last pages and as such, it (and any other thread with a similar false last page) would cause the iPhone app to crash

A new "2014" thread was started which currently has just 12 posts

The same thing happens and the app crashes so perhaps with just a few posts (and less than one page for now), you could take a look at the new thread and figure out what is going wrong (i dunno, may a small thread with few posts is easier to research?)
