Segfault with bind_param

[brinchj]

Hi!
First of all, cool project ;-)

I tried it out (am still new to Rust) and arrived at a segfault. Thought you'd like to know about it if you don't already.

I'm running the master version of both rustsqlite and Rust.

It may just be a transitioning thing (I know Rust is changing and breaking all the time), but it's a bit difficult for me to tell the difference.

Anyway, here's the code:
https://gist.github.com/brinchj/7363049

I tried running the code through valgrind, but it doesn't seem to give me anything useful. Except perhaps that it seems to be telling me that the segfault is in finalize:
==31159== by 0x713477E: sqlite3_finalize (in /usr/lib/x86_64-linux-gnu/libsqlite3.so.0.8.6)
==31159== by 0x5D936C9: cursor::Drop$Cursor::drop::h96b05de1db21bd53ioao::v0.1

If I comment out the bind_param line, the program runs fine. And it only seems to happen with Text. Integer doesn't segfault.
