The script which automates most of the release process runs "make
distcheck", which runs the testsuite, so these tests didn't fail for me
when I made the 1.3.2 release.

topercent2 opens a local disk-based database as well as the one of the
backend type requested, so it can check the same results are given.
It must be the disk-based database which fails, but I can't see why.

I suspect you've ended up with a corrupt cached database, and this
exception isn't actually the same as the original problem (if a test
fails with an exception, the exception type should be reported even
in non-verbose mode, which it wasn't in your original log).

Can you run "make remove-cached-databases" in "tests", and then try
rerunning "./runtest ./apitest --verbose topercent2"?

For the disk-based backends, the test databases are created on demand by
the test harness if a suitable one doesn't exist, so no, you aren't
missing a step.
