Commit f2adbb1065eb introduced abort in _csv module in debug builds in Python 3.3, when using APSW shell.

(You need to have SQLite >=3.7.14 installed.)

$ cd /tmp
$ wget http://apsw.googlecode.com/files/apsw-3.7.14-r2.zip
$ unzip apsw-3.7.14-r2.zip
$ cd apsw-3.7.14-r2
$ python3.3dm setup.py build
...
$ PYTHONPATH="$(ls -d build/lib*)" python3.3dm tools/shell.py
SQLite version 3.7.14.1 (APSW 3.7.14-r2)
