Looks like pysqlite2 pulled in libsqlite3 which is correct. It appears that mod_php is using plain old libsqlite. My guess is that it's an interaction between these two.
Also, apache2, pysqlite2, and libapache2-mod-php5 all have new versions since you reported the bug. Is it still reproducible, or was it perhaps due to only partially updating the system?
