I had the same issue. I re-flashed as it seemed something amongst the repositories or applications I'd previously installed was clashing with Maemo mapper and not allowing it to install properly. Following instructions on installing the libsqlite on its own didn't help matters.

I'm rapidly coming to the conclusion that you have to decide which apps are most important and add them in that order after flashing.
It's a bit of a pain wondering if you should add a new app or repository or not in case it screws up your system but it seems that at least one of the repositories that you've added since re-flashing is borked and causing your problem.

Yeah I had the same. It made no difference. A reflash and install was the only solution I could find that worked.
