This is a weird failure. The test in question marks a directory
unwritable via "chmod a-w" and then tries to perform a database
migration which needs write access to the database. The migration is
expected to fail because the database journal should not be writable to
the directory, but from what I can see in the logs the migration runs
through without erroring out anything.

As the test works for me locally, I think there is something weird on
the test machine. The chmod call seems to go through properly as well
(exit status 0, nothing on stderr), but I suspect that the directory is
still somehow writable for the current user, e.g. because of a dangling
ACL which still allows write access.

One could disable this test or place a guard around it, for example by
creating a file in the directory and check for its existance after the
chmod call. If it does exists, skip the test because the filesystem is
still writable.

Thomas.
