It seems a lot of people are having the same problem as me. I have followed all instructions to download the wikipedia.app and have SFTP'd the .dump file over the iPod. When I open the wikipedia.app and search for something, tapping a search result makes the .app crash and revert to the home screen. I am having the same 'symptoms' as others who, when extracting the 2.2gig dump file, found that the 'wp' folder only came to 56.7mb. Have we missed something? Please help me and many others out.
