When running recent bzr co svn://192.168.1.2/trunk
on Fedora12 x86_64
bazaar crashes with the following backtrace:

bzr: ERROR: sqlite3.ProgrammingError: You must not use 8-bit bytestrings unless you use a text_factory that can interpret 8-bit bytestrings (like text_factory = str). It is highly recommended that you instead just switch your application to Unicode strings.
