[sqlite] Assertion failure in sqlite3pager_get

[Eric Scouten]

I just experienced an application crash due to an assertion failure in 
sqlite3pager_get. This happened while processing a fairly simple 
"update" query.

The assertion that failed was at pager.c, line 2223: assert( 
pPager->journalOpen );

Can anyone help me figure out what I should be looking for? (i.e. a 
misuse of SQLite APIs or a bug in SQLite itself)

We're running SQLite version 3.0.8 on Mac OS X.
